Older versions are not supported anymore and all workarounds for them were removed. Download a prebuilt release of a newer version if you need to use Corrade on older systems (such as Ubuntu 14.04 or Debian 8). This is a conservative change that shouldn't affect any additional distribution compared to the CMake 3.1 requirement in 2019.01. @subsection changelog-latest-new New features - MSVC 2019 compatibility, with slightly less workarounds needed compared to MSVC 2017. See also [mosra/magnum-bootstrap#18](https://github.com/mosra/magnum-bootstrap/issues/18), [mosra/magnum#343](https://github.com/mosra/magnum/pull/343) and [mosra/magnum#354](https://github.com/mosra/magnum/issues/354). - When using Magnum as a CMake subproject, it now puts all binaries into a common directory to simplify `PATH` handling and dynamic plugin loading. For more information see @ref cmake-subproject, [mosra/magnum#357](https://github.com/mosra/magnum/issues/357) and [mosra/magnum-plugins#63](https://github.com/mosra/magnum-plugins/issues/63). - New @ref Image::pixels(), @ref ImageView::pixels() and @ref Trade::ImageData::pixels() accessors for convenient direct access to pixel data of any image - New @ref BasicMutableImageView "MutableImageView*D" and @ref BasicMutableCompressedImageView "MutableCompressedImageView*D" types for mutable views onto image data - Added sRGB BC1-3, BC4, BC5, BC6h, BC7, ETC2, EAC, 2D/3D ASTC and PVRTC formats to @ref CompressedPixelFormat as well as their conversion to corresponding GL/Vulkan formats in @ref GL::compressedPixelFormat() and @ref Vk::vkFormat(Magnum::CompressedPixelFormat) - New @ref PixelFormat::R8Srgb, @ref PixelFormat::RG8Srgb, @ref PixelFormat::RGB8Srgb and @ref PixelFormat::RGBA8Srgb sRGB pixel formats as well as their conversion to corresponding GL/Vulkan formats in @ref GL::pixelFormat() and @ref Vk::vkFormat(Magnum::PixelFormat) - New @ref compressedBlockSize() and @ref compressedBlockDataSize() utilities for querying parameters of @ref CompressedPixelFormat entries, similar to what @ref pixelSize() is for @ref PixelFormat @subsubsection changelog-latest-new-audio Audio library - Ability to (un)queue buffers in @ref Audio::Source (see [mosra/magnum#338](https://github.com/mosra/magnum/pull/338)) - Added getters for basic @ref Audio::Buffer properties (see [mosra/magnum#342](https://github.com/mosra/magnum/pull/342)) - Implemented support for @al_extension{SOFT,loop_points} in @ref Audio::Buffer (see [mosra/magnum#342](https://github.com/mosra/magnum/pull/342)) - @ref Audio::Context can now take command-line arguments and supports the `--magnum-log` and `--magnum-disable-extensions` options similarly to @ref GL::Context (see [mosra/magnum#362](https://github.com/mosra/magnum/pull/362)) @subsubsection changelog-latest-new-debugtools DebugTools library - New @ref DebugTools::screenshot() function for convenient saving of screenshots - @ref DebugTools::CompareImage and variants now properly handle floating-point specials such as NaN or @f$ \infty @f$ in compared data - @ref DebugTools::CompareImageFile and @ref DebugTools::CompareImageToFile now support the new @ref TestSuite-Tester-save-diagnostic "--save-diagnostic option", making it possible to save images when a comparison fails - @ref DebugTools::CompareImage and variants can now print a verbose diagnostic also if the `--verbose` @ref TestSuite-Tester-command-line "command-line option" is specified and comparison delta is non-zero - @ref DebugTools::CompareImage and @ref DebugTools::CompareImageToFile now accept also @ref Corrade::Containers::StridedArrayView2D on the left side of the comparison for added flexibility. See @ref DebugTools-CompareImage-pixels for more infromation. @subsubsection changelog-latest-new-gl GL library - Additions to @ref GL::CompressedPixelFormat and compressed @link GL::TextureFormat @endlink: - sRGB S3TC formats as defined by the @gl_extension{EXT,texture_sRGB} desktop, @gl_extension{EXT,texture_compression_s3tc_srgb} ES and @webgl_extension{WEBGL,compressed_texture_s3tc_srgb} WebGL extension - Recognizing @gl_extension{EXT,texture_compression_dxt1} desktop and ES extension and the @gl_extension2{ANGLE,texture_compression_dxt1,ANGLE_texture_compression_dxt} / @gl_extension2{ANGLE,texture_compression_dxt3,ANGLE_texture_compression_dxt} / @gl_extension2{ANGLE,texture_compression_dxt5,ANGLE_texture_compression_dxt} family of extensions in order to enable S3TC formats on a wider range of OpenGL ES devices - Recognizing the @gl_extension{KHR,texture_compression_astc_sliced_3d} extension - @gl_extension{EXT,texture_compression_rgtc} / @gl_extension{EXT,texture_compression_bptc} OpenGL ES and @webgl_extension{EXT,texture_compression_rgtc} / @webgl_extension{EXT,texture_compression_bptc} WebGL extensions, complementing the desktop support for BC4, BC5, BC6H and BC7 formats - @webgl_extension{WEBGL,texture_compression_astc} WebGL extension, complementing the desktop and ES support for ASTC - @gl_extension{OES,texture_compression_astc} OpenGL ES extension, adding 3D ASTC compression (unfortunately there's no desktop equivalent yet) - PVRTC formats defined by the @gl_extension{IMG,texture_compression_pvrtc} / @gl_extension{IMG,pvrtc_sRGB} OpenGL ES and @webgl_extension{WEBGL,compressed_texture_pvrtc} WebGL extensions - Implemented @gl_extension{EXT,texture_sRGB_R8} and @gl_extension{EXT,texture_sRGB_RG8} extensions adding @ref GL::TextureFormat::SR8 and @ref GL::TextureFormat::SRG8 formats to complement new sRGB formats in @ref GL::PixelFormat - Added ES-only @ref GL::TextureFormat::BGRA and @ref GL::TextureFormat::BGRA8 and clarified their purpose in relation to @ref GL::PixelFormat::BGRA - New @ref GL::AbstractFramebuffer::implementationColorReadFormat() and @ref GL::AbstractFramebuffer::implementationColorReadType() queries for more robust checks when doing framebuffer readbacks; together with three new workarounds @cpp "nv-implementation-color-read-format-dsa-broken" @ce, @cpp "intel-windows-implementation-color-read-format-completely-broken" @ce and @cpp "mesa-implementation-color-read-format-dsa-explicit-binding" @ce, because it's 2019 and GL drivers are *still* awful. See @ref opengl-workarounds for more information. - Added @ref GL::BufferTexture::size() as it was the only texture type were this query was missing. - New @cpp "swiftshader-no-es2-draw-instanced-entrypoints" @ce and @cpp "swiftshader-no-es2-oes-texture-3d-entrypoints" @ce workarounds disabling @gl_extension{ANGLE,instanced_arrays} and @gl_extension{OES,texture_3D} extensions on SwiftShader due to missing suffixed entry points. See @ref opengl-workarounds for more information. - New @cpp "swiftshader-broken-xfb-buffer-binding-target" @ce workaround that's fixing misbehaving buffers when using @ref GL::Buffer::TargetHint::TransformFeedback. See @ref opengl-workarounds for more information. - New pseudo-extension `GL_MAGNUM_shader_vertex_id` denoting support of the @glsl gl_VertexID @ce shader builtin. Present on all GL 3.0+, GLES 3.0+ and WebGL 2 contexts, but disabled for SwiftShader as its support is broken (see the @cpp "swiftshader-broken-shader-vertex-id" @ce workaround in @ref opengl-workarounds for more information). This pseudo-extension can be also explicitly disabled using the usual `--magnum-disable-extensions` @ref GL-Context-command-line "command-line option" for testing purposes. - An assorted collection of workarounds for Intel Windows drivers "fixing" various issues related to @gl_extension{ARB,direct_state_access} by using a non-DSA code path in the affected cases --- see @ref opengl-workarounds for more information: - @cpp "intel-windows-buggy-dsa-bufferdata-for-index-buffers" @ce fixing a nasty hard-to-reproduce synchronization bug when @ref GL::Buffer::setData() is followed by @ref GL::Mesh::setIndexBuffer() - @cpp "intel-windows-broken-dsa-for-cubemaps" @ce fixing everything about @ref GL::CubeMapTexture (see [mosra/magnum-examples#55](https://github.com/mosra/magnum-examples/issues/55)) - @cpp "intel-windows-half-baked-dsa-texture-bind" @ce fixing texture binding inconsistencies (affected [mosra/magnum-examples#55](https://github.com/mosra/magnum-examples/issues/55) as well) - @cpp "intel-windows-broken-dsa-layered-cubemap-array-framebuffer-attachment" @ce fixing @ref GL::Framebuffer::attachLayeredTexture() with @ref GL::CubeMapTextureArray - @cpp "intel-windows-broken-dsa-framebuffer-clear" @ce fixing @ref GL::Framebuffer::clearColor() - @cpp "intel-windows-broken-dsa-indexed-queries" @ce fixing @ref GL::PrimitiveQuery::begin(UnsignedInt) - @cpp "intel-windows-broken-dsa-integer-vertex-attributes" @ce fixing @ref GL::Mesh::addVertexBuffer() with @ref Magnum::Short "Short" attributes - New @cpp "arm-mali-timer-queries-oom-in-shell" @ce workaround for @ref GL::Context::DetectedDriver::ArmMali "ARM Mali" drivers on Android disabling the @gl_extension{EXT,disjoint_timer_query} extension in Android shell (as opposed to an APK) because using it causes the @ref GL::Renderer::Error::OutOfMemory error. See @ref opengl-workarounds for more information. - New `--magnum-gpu-validation` @ref GL-Context-command-line "command-line option" and a corresponding environment variable to conveniently enable @gl_extension{KHR,debug} debug output. This flag also causes @ref Platform::Sdl2Application::GLConfiguration::Flag::Debug "GLConfiguration::Flag::Debug" to be enabled for context creation on both windowed and windowless applications - Detection of SwiftShader and ARM Mali drivers with @ref GL::Context::DetectedDriver::SwiftShader and @ref GL::Context::DetectedDriver::ArmMali - It's now possible to pass @ref std::initializer_list to @ref GL::Buffer::setData() / @ref GL::Buffer::setSubData() for a succint upload of basic types - Added an ability to use Magnum with multiple OpenGL contexts using @ref GL::Context::makeCurrent(), see @ref GL-Context-multiple for more information - @ref GL::AbstractFramebuffer::read(), @ref GL::Texture::image(), @ref GL::Texture::subImage(), @ref GL::Texture::compressedImage(), @ref GL::Texture::setCompressedSubImage() and equivalent APIs in other texture classes now can read the pixels into @ref BasicMutableImageView "MutableImageView*D" and @ref BasicMutableCompressedImageView "MutableCompressedImageView*D" as well - @ref GL::hasTextureFormat() and @ref GL::textureFormat() helpers for converting @ref PixelFormat / @ref CompressedPixelFormat to @ref GL::TextureFormat, similar to @ref GL::hasPixelFormat() / @ref GL::pixelFormat() used for converting to @ref GL::PixelFormat @subsubsection changelog-latest-new-math Math library - @ref Math::Frustum::begin() / @ref Math::Frustum::end() accessors for easy range-for access to @ref Math::Frustum planes - New @ref Math::Matrix4::perspectiveProjection(const Vector2&, const Vector2&, T, T) overload for calculating off-center projection matrices - @ref Color3ub and @ref Color4ub can be printed with @ref Corrade::Utility::Debug as actual colors using the @ref Corrade::Utility::Debug::color modifier - Added convenience @ref BoolVector2, @ref BoolVector3 and @ref BoolVector4 typedefs to the root namespace - New @ref Math::IsScalar, @ref Math::IsVector, @ref Math::IsIntegral, @ref Math::IsFloatingPoint and @ref Math::IsUnitless type traits and a @ref Math::UnderlyingTypeOf utility - Added batch versions of @ref Math::isInf() and @ref Math::isNan() - Scalar and vector @ref Math::equal() and @ref Math::notEqual() which do a component-wise comparison in the vector case, as the equality/non-equality operators return a single @cpp bool @ce - @ref Math::scatter() as an inverse operation to @ref math::gather(), both functions now support addressing via component indices as well @subsubsection changelog-latest-new-meshtools MeshTools library - @ref MeshTools::duplicateInto() alternative to @ref MeshTools::duplicate() that writes the output to an existing location - @ref MeshTools::generateFlatNormalsInto() alternative to @ref MeshTools::generateFlatNormals() that writes the output to an existing location - @ref MeshTools::generateSmoothNormals() for generating weighted smooth normals of indexed meshes (see [mosra/magnum#229](https://github.com/mosra/magnum/pull/229)) - @ref MeshTools::compile(const Trade::MeshData3D&, CompileFlags) now accepts optional flags to control normal generation @subsubsection changelog-latest-new-platform Platform libraries - Added @ref Platform::EmscriptenApplication, implementing a lightweight and more flexible alternative to @ref Platform::Sdl2Application for Emscripten. This is now the recommended application to use for WebGL builds. See [mosra/magnum#300](https://github.com/mosra/magnum/pull/300) and [mosra/magnum-bootstrap#17](https://github.com/mosra/magnum-bootstrap/pull/17). - @ref Platform::Sdl2Application and @ref Platform::GlfwApplication are now DPI-aware on Windows as well. See their documentation, @ref platforms-windows-hidpi, [mosra/magnum#243](https://github.com/mosra/magnum/issues/243) and [mosra/magnum#349](https://github.com/mosra/magnum/pull/349) for more information. - Added @ref Platform::Sdl2Application::glContext() to access the underlying `SDL_GLContext` (see [mosra/magnum#325](https://github.com/mosra/magnum/pull/325)) - Added @ref Platform::Sdl2Application::setMinWindowSize() and @ref Platform::Sdl2Application::setMinWindowSize() + equivalent APIs for @ref Platform::GlfwApplication (see [mosra/magnum#335](https://github.com/mosra/magnum/pull/335)) - New [base-wxwidgets](https://github.com/mosra/magnum-bootstrap/tree/base-wxwidgets) bootstrap project for using Magnum together with wxWidgets (see [mosra/magnum-bootstrap#19](https://github.com/mosra/magnum-bootstrap/pull/19)) - Added @ref Platform::Sdl2Application::setWindowTitle() (and equivalents in @ref Platform::GlfwApplication and @ref Platform::EmscriptenApplication) for changing window title at runtime as opposed to setting them on application startup - @ref Platform::WindowlessEglApplication now uses the @m_class{m-doc-external} [EGL_EXT_device_enumeration](https://www.khronos.org/registry/EGL/extensions/EXT/EGL_EXT_device_enumeration.txt), @m_class{m-doc-external} [EGL_EXT_platform_base](https://www.khronos.org/registry/EGL/extensions/EXT/EGL_EXT_platform_base.txt) and @m_class{m-doc-external} [EGL_EXT_platform_device](https://www.khronos.org/registry/EGL/extensions/EXT/EGL_EXT_platform_device.txt) extensions where available instead of `EGL_DEFAULT_DISPLAY`, working better on headless setups and allowing selection of an arbitrary GPU device on multi-GPU systems @subsubsection changelog-latest-new-primitives Primitives library - @ref Primitives::circle2DSolid() and @ref Primitives::circle3DSolid() can now generate a textured mesh @subsubsection changelog-latest-new-scenegraph SceneGraph library - Added @ref SceneGraph::AbstractObject::Type / @ref SceneGraph::AbstractFeature::Type / @ref SceneGraph::AbstractFeatureGroup::Type typedefs and @ref SceneGraph::AbstractObject::Dimensions / @ref SceneGraph::AbstractFeature::Dimensions / @ref SceneGraph::AbstractFeatureGroup::Dimensions constants for querying underlying type and dimension template parameters @subsubsection changelog-latest-new-shaders Shaders library - Normal texture support in @ref Shaders::Phong - Added @ref Shaders::Generic3D::Tangent generic vertex attribute definition - Object ID output in @ref Shaders::Flat and @ref Shaders::Phong - Vertex color support in @ref Shaders::Flat and @ref Shaders::Phong @subsubsection changelog-latest-new-text Text library - A new @ref Text::AbstractGlyphCache base now makes @ref Text::AbstractFont and @ref Text::AbstractFontConverter independent on the graphics API used, meaning the @ref Text library now has just an optional dependency on @ref GL. The @ref Text::Renderer, @ref Text::GlyphCache and @ref Text::DistanceFieldGlyphCache classes are now built only if `TARGET_GL` is enabled (done by default). - New @ref Text::AbstractFont::setFileCallback() to allow opening multi-file fonts with an API similar to @ref Trade::AbstractImporter @subsubsection changelog-latest-new-trade Trade library - The @ref magnum-imageconverter "magnum-imageconverter" utility now implements new `-i` / `--importer-options` and `-c` / `--converter-options` command-line options for setting plugin-specific configuration @subsection changelog-latest-changes Changes and improvements - The @ref ResourceManager class now accepts also @ref Corrade::Containers::Pointer instances in addition to raw pointers - The @ref AbstractResourceLoader::set() function now accepts also @cpp nullptr @ce for explicitly setting @ref ResourceDataState::Loading or @ref ResourceDataState::NotFound resources - Added comparison operators to @ref Resource (see [mosra/magnum#346](https://github.com/mosra/magnum/pull/346)) - @ref ImageView and @ref CompressedImageView of smaller dimension count are now implicitly convertible to views of higher dimension count to make slice-by-slice uploads to @ref GL::TextureArray and others easier - @ref Image::data(), @ref CompressedImage::data() and @ref Trade::ImageData::data() called on a r-value now return @ref Corrade::Containers::Array instead of being deleted - Global state used by @ref GL::Context and @ref Audio::Context is no longer duplicated when Magnum is built statically and linked to more than one dynamic library or executable. Currently that holds only for Linux and macOS, Windows support will come next. - The [base-qt](https://github.com/mosra/magnum-bootstrap/tree/base-qt) bootstrap project is fixed to use OpenGL 4.1 on macOS instead of being stuck on 2.1 (see [mosra/magnum-bootstrap#22](https://github.com/mosra/magnum-bootstrap/issues/22)) @subsubsection changelog-latest-changes-animation Animation library - Default extrapolation of @ref Animation::TrackView was changed from @ref Animation::Extrapolation::Extrapolated to @ref Animation::Extrapolation::Constant to be consistent with @ref Animation::Track @subsubsection changelog-latest-changes-audio Audio library - The @ref Audio::AnyImporter "AnyAudioImporter" plugin now correctly recognizes also uppercase file extensions (see [mosra/magnum#312](https://github.com/mosra/magnum/pull/312)) @subsubsection changelog-latest-changes-debugtools DebugTools library - @ref DebugTools::CompareImage, @ref DebugTools::CompareImageToFile and other variants are now usable directly through @ref CORRADE_COMPARE_AS(), no need to pass an explicit instance to @ref CORRADE_COMPARE_WITH() when just the default parameters are needed - @ref DebugTools::textureSubImage() for float textures was updated to work with SwiftShader (which has broken @glsl gl_VertexID @ce) @subsubsection changelog-latest-changes-gl GL library - Fully dropped support for @gl_extension{EXT,direct_state_access}. All contemporary drivers supporting @gl_extension{EXT,direct_state_access} support the (newer and better designed) @gl_extension{ARB,direct_state_access}, while drivers that don't support the ARB version don't support the EXT flavor either. See also [mosra/magnum#81](https://github.com/mosra/magnum/issues/81). - Reworked @ref GL::Mesh internals to make use of @gl_extension{ARB,direct_state_access} instead of being the last code path stuck on @gl_extension{EXT,direct_state_access} - @ref GL::DebugOutput::setCallback() no longer assumes the debug message callback is called from the same thread as the one with the corresponding GL context (which is the case on Mesa AMD drivers). The documentation was updated to reflect that as well. - @ref GL::AbstractTexture::unbindImage() "GL::*Texture::unbindImage()" now uses a RGBA format instead of a single-channel format because @ref GL::Context::DetectedDriver::ArmMali "ARM Mali" drivers complain about R8 not being renderable (even though the format shouldn't matter when unbinding a texture) - The engine was silently doing an explicit initial call to @fn_gl{Viewport} when it detected it's running under ApiTrace, because otherwise ApiTrace would assume a zero-sized framebuffer. This behavior is no longer silent but advertised as a @cpp "apitrace-zero-initial-viewport" @ce workaround. See @ref opengl-workarounds for more information. - Added a @cpp "nv-egl-forward-compatible-context-unhappy" @ce workaround that removes @ref Platform::WindowlessEglApplication::Configuration::Flag::ForwardCompatible from flags passed to `eglCreateContext()` as that otherwise causes NVidia to fail with `EGL_BAD_MATCH`. See @ref opengl-workarounds for more information. - @ref GL::OpenGLTester no longer implicitly enables @ref GL::DebugOutput as it can be quite spammy when complex shaders or benchmarks are allowed. For easier debugging, users are encouraged to use the new `--magnum-gpu-validation` @ref GL-Context-command-line "command line option" instead. - Added an ability to create @ref GL::DynamicAttribute directly from a @ref GL::Attribute @subsubsection changelog-latest-changes-math Math library - @ref Math::BoolVector now implements component-wise @cpp && @ce, @cpp || @ce and @cpp ! @ce for better consistency with boolean operations done on scalar types - Construction using @ref Math::ZeroInit and @ref Math::IdentityInit is now explicit, to be consistent with @ref Math::NoInit construction and avoid ambiguous cases - All scalar/vector functions in the @ref Math namespace now work also with special types such as @ref Deg or @ref Rad --- the only exception is power functions such as @ref Math::sqrt() or @ref Math::log(), as the resulting unit can't be represented. Those accept only unitless types. - All batch functions in @ref Magnum/Math/FunctionsBatch.h now accept @ref Corrade::Containers::StridedArrayView instead of a dense array view to make them usable in more contexts - @ref Math::Vector::min(), @ref Math::Vector::max(), @ref Math::Vector::minmax() and batch @ref Math::min(Containers::StridedArrayView1D), @ref Math::max(Containers::StridedArrayView1D) and @ref Math::minmax(Containers::StridedArrayView1D) functions now ignore NaNs in the data, if possible. Use @ref Math::isNan(const Vector&) or the batch @ref Math::isNan(Containers::StridedArrayView1D) to detect presence of NaN values if needed. - Changed the way @ref Math::operator<<(Corrade::Utility::Debug&, const BoolVector&) works --- the output now has the same bit order as when constructing it using binary literals - @ref Math::sincos() now uses the `__builtin_sincos` intrinsic on GCC, making it potentially faster in case the optimizer doesn't figure out the same - @ref Math::Vector::operator-() and @ref Math::Vector2::perpendicular() are now enabled only for signed types to prevent accidents @subsubsection changelog-latest-changes-meshtools MeshTools library - @ref MeshTools::fullScreenTriangle() was updated to work on ES3 SwiftShader contexts (which have broken @glsl gl_VertexID @ce) - @ref MeshTools::interleave() and @ref MeshTools::interleaveInto() now works also with @ref Corrade::Containers::ArrayView, @ref Corrade::Containers::StridedArrayView and friends @subsubsection changelog-latest-changes-shaders Shaders library - @ref Shaders::Phong now clamps the specular factor to minimize artifacts when shininess is near zero - @ref Shaders::Phong can now handle zero lights, in which case its output is equivalent to @ref Shaders::Flat3D. See @ref Shaders-Phong-zero-lights for more information. - @ref Shaders::MeshVisualizer is fixed to work properly on Intel Windows drivers, adding a new @cpp "intel-windows-explicit-uniform-location-is-less-explicit-than-you-hoped" @ce workaround @subsubsection changelog-latest-changes-texturetools TextureTools library - @ref TextureTools::distanceField() was updated to work on ES3 SwiftShader contexts (which have broken @glsl gl_VertexID @ce) @subsubsection changelog-latest-changes-platform Platform libraries - @ref Platform::Sdl2Application::anyEvent() is now fired also for window events that are not exposed through @ref Platform::Sdl2Application::viewportEvent() "viewportEvent()" or @ref Platform::Sdl2Application::exitEvent() "exitEvent()" - On OpenGL ES builds, @ref Platform::Sdl2Application now tells SDL whether to use a system GL driver or a dedicated GLES driver based on whether @ref MAGNUM_TARGET_DESKTOP_GLES is defined. This allows for a smoother experience for example when using ANGLE on Windows. See @ref Platform-Sdl2Application-usage-gles for more information. - Replaced uses of `Pointer_stringify()` in @ref Platform::Sdl2Application which was removed in Emscripten 1.38.27 - @ref Platform::Sdl2Application and all Emscripten markup was updated to work correctly both with the [`-s DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR=1`](https://github.com/emscripten-core/emscripten/pull/7977) option available since Emscripten 1.38.27 and with older versions - @ref Platform::WindowlessEglApplication was adapted to properly create WebGL 2 contexts both in Emscripten 1.38.24 and in older versions - @ref Platform::Sdl2Application::exit() and @ref Platform::GlfwApplication::exit() now have an optional parameter to specify the actual application return code (see [mosra/magnum#332](https://github.com/mosra/magnum/pull/332)) - @ref Platform::GlfwApplication and @ref Platform::EmscriptenApplication now implement @ref Platform::GlfwApplication::MouseMoveEvent::relativePosition() as well for better compatibility with @ref Platform::Sdl2Application. The relative position is not supplied by the underlying toolkits, so it's emulated on the application side. - Extended @ref Platform::BasicScreen with @ref Platform::BasicScreen::mouseScrollEvent() "mouseScrollEvent()", @ref Platform::BasicScreen::textInputEvent() "textInputEvent()" and @ref Platform::BasicScreen::textEditingEvent() "textEditingEvent()" on application implementations that provide such events - @ref Platform::BasicScreenedApplication is now available also for @ref Platform::AndroidApplication - New @ref Platform::BasicScreen::BasicScreen(BasicScreenedApplication&, PropagatedEvents) constructor that directly adds the newly-created screen to an application in a RAII manner, without needing to explicitly call @ref Platform::BasicScreenedApplication::addScreen() and @ref Platform::BasicScreen::setPropagatedEvents() later - @ref Platform::BasicScreen::application() now returns a reference instead of a pointer, checking that the screen is actually added to the application. Users are encouraged to call @ref Platform::BasicScreen::hasApplication() to check if the application is accessible. @subsubsection changelog-latest-changes-text Text library - For consistency with @ref Trade::AbstractImporter, @ref Text::AbstractFont now doesn't fail when opening empty files --- instead this is handled in the particular plugin implementations - @ref Text::AbstractFont::size(), @ref Text::AbstractFont::ascent(), @ref Text::AbstractFont::descent() and @ref Text::AbstractFont::lineHeight() now expect that a font is opened, consistently with other accessor functions @subsubsection changelog-latest-changes-trade Trade library - The @ref Trade::AnyImageImporter "AnyImageImporter", @ref Trade::AnyImageConverter "AnyImageConverter" and @ref Trade::AnySceneImporter "AnySceneImporter" plugins now correctly recognize also uppercase file extensions (see [mosra/magnum#312](https://github.com/mosra/magnum/pull/312)) @ref Trade::TgaImporter "TgaImporter" now properly reports an error message when opening an empty file - @ref Trade::AbstractImporter::setFileCallback() now accepts callbacks with @cpp const @ce references to user data as well - @ref Trade::AnyImageImporter "AnyImageImporter" and @ref Trade::AnyImageConverter "AnyImageConverter" plugins now recognize Basis Universal files (see [mosra/magnum#370](https://github.com/mosra/magnum/pull/370)) @subsection changelog-latest-buildsystem Build system - @ref building-packages-msys "MSYS2 packages" are now in official repositories, installable directly via `pacman` - Plugin search path on Windows is now discovered relative to location of the @ref Trade, @ref Text or @ref Audio library DLL instead of executable location. That makes it behave better in case Magnum is installed via a package and the installation directory hardcoded at build time doesn't exist on the target machine (which is the case of MSYS2 packages). - `FindSDL2.cmake` was updated to work with MinGW version 2.0.5 and newer, since these dropped the old directory hierarchy. Older versions have both the original and the new hierarchy, so it should work with these as well. - `FindSDL2.cmake` now points `SDL2_INCLUDE_DIR` to the root and the @ref Platform::Sdl2Application was updated to follow that; people using custom buildsystems don't need to add `SDL2/` to their include path anymore - When using Magnum as a CMake subproject, @ref Platform::GlfwApplication and @ref Platform::Sdl2Application now copy the GLFW / SDL2 DLLs to `CMAKE_RUNTIME_OUTPUT_DIRECTORY` (if set) as a post-build step. The DLL location, if found, is also available through `GLFW_DLL` and `SDL2_DLL_RELEASE` / `SDL2_DLL_DEBUG` variables for use by 3rd party code. See also [mosra/magnum#347](https://github.com/mosra/magnum/pull/347) for more information. - Updated *extremely* outdated Emscripten boilerplate from the [base-emscripten bootstrap project](https://github.com/mosra/magnum-bootstrap/tree/base-emscripten) (the HTML markup was unchanged since 2013, heh) - ES 2.0 and ES 3.0 subset of tests requiring GL context is now run on Travis CI using SwiftShader for better code coverage - On CMake 3.13 and up, WebGL2 build on Emscripten (and the `-s USE_WEBGL2=1` flag in particular) is now handled by the `FindOpenGLES3.cmake` module and the new `INTERFACE_LINK_OPTIONS` property instead of `FindMagnum.cmake`. On older versions this is handled in `FindMagnum.cmake` by modifying the global `CMAKE_EXE_LINKER_FLAGS` variable. - It's now possible to use Magnum as a CMake subproject also when building for Emscripten (see [mosra/magnum#219](https://github.com/mosra/magnum/issues/219)) - Updated the Vcpkg package to work correctly with Vcpkg's own SDL2 (see [Microsoft/vcpkg#5730](https://github.com/Microsoft/vcpkg/pull/5730)) - Updated bundled GL headers to properly define the `GL_VERSION_*` macros to avoid conflicting `GLintptr` and `GLsizeiptr` type definitions on Windows when using Magnum together with Qt - It's now possible to override CMake's [OpenGL_GL_PREFERENCE](https://cmake.org/cmake/help/v3.11/module/FindOpenGL.html#linux-specific) from outside on systems where GLVND doesn't work properly (before the build scripts and `FindMagnum.cmake` always forced GLVND) - `FindMagnum.cmake` now correctly finds debug versions of statically built plugins when using Vcpkg - `FindEGL.cmake`, `FindOpenAL.cmake`, `FindOpenGLES2.cmake` and `FindOpenGLES3.cmake` now explicitly link to the `GL` and `openal` libraries on Emscripten, which is needed for `MINIMAL_BUILD` - `FindOpenGLES2.cmake` and `FindOpenGLES3.cmake` don't require GL ES headers to be installed on the system anymore, as Magnum uses its own copies - Fixed linking of static `Any*` plugins when the libraries are otherwise build as dynamic - Removed mention of the outdated Ubuntu PPA from @ref building as it doesn't seem to be maintained anymore (see [mosra/magnum-examples#61](https://github.com/mosra/magnum-examples/issues/61)) - Worked around a bug in the NVCC compiler on Windows involving @ref Math::RectangularMatrix::DiagonalSize to make Magnum usable with CUDA (see [mosra/magnum#345](https://github.com/mosra/magnum/issues/345)) - Fixed a 64-to-32-bit conversion warning on MSVC in @ref GL::Mesh internals (see [mosra/magnum#352](https://github.com/mosra/magnum/issues/352)) - Emscripten builds now have the `-fPIC` option disabled by default as it causes linker errors related to `__memory_base` on 1.38.36 (see also [emscripten-core/emscripten#8761](https://github.com/emscripten-core/emscripten/issues/8761)) - Fixed the `Magnum::Application`, `Magnum::WindowlessApplication` and `Magnum::GLContext` aliases in `FindMagnum.cmake` to propagate the values from the target they alias also across directories, instead of failing with e.g. Error evaluating generator expression: $ Target "Magnum::Sdl2Application" not found. @subsection changelog-latest-bugfixes Bug fixes - Fixed compilation of the @ref Vk library on 32-bit Windows - @ref Math::pack() was incorrectly not selecting the nearest integral value, causing @ref Math::Color3::toSrgbInt() to not roundtrip, among other things. - The @cb{.cmake} android_create_apk() @ce macro for @ref platforms-android-apps-cmake "Gradle-less Android builds" now properly creates the library output directory beforehand - Fixed a bad interaction of @ref GL::Mesh and @ref GL::Buffer state trackers resulting in corrupted rendering on ES/WebGL platforms and systems without @gl_extension{ARB,direct_state_access} - Fixed @ref GL::Mesh instanced drawing to properly take into account all five @gl_extension{ANGLE,instanced_arrays}, @gl_extension{EXT,instanced_arrays}, @gl_extension{EXT,draw_instanced}, @gl_extension{NV,instanced_arrays} and @gl_extension{NV,draw_instanced} extensions - @ref Platform::GLContext would crash on destruction if it was constructed with @ref NoCreate but @ref Platform::GLContext::create() was never called (see [mosra/magnum#331](https://github.com/mosra/magnum/pull/331) - Reading of float textures on ES3 contexts using @ref DebugTools::textureSubImage() returned a zero-sized image by accident - @ref MeshTools::compile() was producing an incorrect mesh when @ref Trade::MeshData3D had both colors and texture coordinates - Properly zero-initializing the UTF-8 buffer in @ref Platform::GlfwApplication::textInputEvent() (see [mosra/magnum#324](https://github.com/mosra/magnum/pull/324)) - @ref Platform::Sdl2Application::viewportEvent() and @ref Platform::GlfwApplication::viewportEvent() is fixed to behave correctly with @ref platforms-macos-hidpi "Retina-aware" apps on macOS/iOS - @ref Text::AbstractFontConverter::exportFontToFile() and @ref Text::AbstractFontConverter::exportGlyphCacheToFile() now properly returns failure when the underlying data export function returns an empty list of files - Updated the `base-qt` bootstrap project to correctly reset state tracker when going from and back to Qt code, and to use the framebuffer provided by Qt instead of @ref GL::defaultFramebuffer (see [mosra/magnum#322](https://github.com/mosra/magnum/issues/322) and [mosra/magnum-bootstrap#15](https://github.com/mosra/magnum-bootstrap/pull/15)) - @ref Trade::TgaImporter "TgaImporter" now properly handles files with too short data (see [mosra/magnum#359](https://github.com/mosra/magnum/issues/359)) - When context creation fails *really bad* with @ref Platform::Sdl2Application, @ref Platform::GlfwApplication, @ref Platform::WindowlessGlxApplication or @ref Platform::WindowlessWglApplication, driver detection for the @cpp "no-forward-compatible-core-context" @ce now properly handles @fn_gl{GetString} returning a @cpp nullptr @ce - @ref GL::Texture::imageSize() was present on WebGL 2 by mistake (see [mosra/magnum#365](https://github.com/mosra/magnum/pull/365)) - @ref GL::BufferTexture::setBuffer() now creates the passed buffer if not already (and if it was not created by @fn_gl{CreateBuffers}). Before that, passing a freshly created @ref GL::Buffer to it was causing @ref GL::Renderer::Error::InvalidOperation on systems without @gl_extension{ARB,direct_state_access}. - Fixed @ref Shaders::Vector and @ref Shaders::DistanceFieldVector to work on iOS, which has only 8 texture binding slots in total (see [mosra/magnum-examples#65](https://github.com/mosra/magnum-examples/issues/65) and [mosra/magnum#374](https://github.com/mosra/magnum/pull/374)) @subsection changelog-latest-docs Documentation - Extended @ref platforms-html5-code-size "Emscripten" documentation with available compiler switches for code size / compile time tradeoffs (instead of unconditionally enabling them by default, see [mosra/magnum#211](https://github.com/mosra/magnum/issues/211)) - Fixed Gentoo build instructions (see [mosra/magnum#344](https://github.com/mosra/magnum/pull/344)) - Various documentation improvements and copy editing (see [mosra/magnum#361](https://github.com/mosra/magnum/pull/361)) - Populating the Troubleshooting section of @ref platforms-windows "Windows-specific platform notes" (see [mosra/magnum#355](https://github.com/mosra/magnum/issues/355)) - Extended info about the `--head` option in @ref building-packages-vcpkg (see [mosra/magnum#367](https://github.com/mosra/magnum/issues/367)) - The @ref getting-started "Getting Started Guide" was rewritten to be easier to follow for Windows users, removing usual pain points (see [mosra/magnum#378](https://github.com/mosra/magnum/issues/378)) @subsection changelog-latest-deprecated Deprecated APIs - @cpp Math::Color3::Hsv @ce and @cpp Math::Color4::Hsv @ce tuple typedefs are deprecated in favor of tuple-less @ref Math::ColorHsv, working correctly with the usual @ref Math::NoInit / @ref Math::ZeroInit tags while being faster to compile - @cpp Math::Frustum::planes() @ce are deprecated due to redundancy, use either @ref Math::Frustum::operator[](), @ref Math::Frustum::data() or range access using @ref Math::Frustum::begin() / @ref Math::Frustum::end() - Batch @ref Math::min(Containers::StridedArrayView1D), @ref Math::max(Containers::StridedArrayView1D) and @ref Math::minmax(Containers::StridedArrayView1D) are moved to a new @ref Magnum/Math/FunctionsBatch.h header in order to speed up compile times. This header is included from @ref Magnum/Math/FunctionsBatch.h when building with @ref MAGNUM_BUILD_DEPRECATED enabled, include it explicitly to ensure forward compatibility - @cpp Trade::ImporterFileCallbackPolicy @ce is deprecated as it was moved to @ref InputFileCallbackPolicy in the root namespace to be shared with APIs outside of the @ref Trade namespace. Moreover, @cpp InputFileCallbackPolicy::LoadPernament @ce is deprecated due to a typo, use @ref InputFileCallbackPolicy::LoadPermanent instead. - @cpp DebugTools::ForceRendererOptions::scale() @ce is deprecated in favor of @ref DebugTools::ForceRendererOptions::size(), as that's more consistent with the documentation and the corresponding setter. - @cpp Text::AbstractFont::openSingleData() @ce and @cpp Text::AbstractFont::openData() @ce taking a list of files are deprecated in favor of @ref Text::AbstractFont::openData(Containers::ArrayView, Float) and @ref Text::AbstractFont::setFileCallback() - @ref GL::Buffer::setData() and @ref GL::Buffer::setSubData() no longer has overloads taking @ref std::vector / @ref std::array, but instead relies on @ref Corrade/Containers/ArrayViewStl.h to provide conversion from these to @ref Corrade::Containers::ArrayView. This header is included automatically when @ref MAGNUM_BUILD_DEPRECATED is enabled, include it explicitly to stay forward compatible. - @cpp GL::TextureFormat::R3B3G2 @ce had a misleading typo in the name, use @ref GL::TextureFormat::R3G3B2 instead. - @ref GL::AbstractTexture destructor is now @cpp protected @ce on builds with @ref MAGNUM_BUILD_DEPRECATED disabled in order to avoid accidents with subclass destructors not being called. Right now all subclasses themselves have trivial destruction, but that may change in the future due to driver workarounds being added. - @cpp Magnum/MeshTools/GenerateFlatNormals.h @ce is deprecated, use @cpp Magnum/MeshTools/GenerateNormals.h @ce instead - @cpp MeshTools::generateFlatNormals(const std::vector&, const std::vector&) @ce is deprecated for doing too many things at once and being too tied to one particular STL container, use @ref MeshTools::generateFlatNormals(const Containers::StridedArrayView1D&) instead - Templated versions of @ref Image::data(), @ref ImageView::data(), @ref CompressedImage::data(), @ref CompressedImageView::data() and @ref Trade::ImageData::data() that returned a raw pointer are deprecated, use the non-templated version together with @ref Corrade::Containers::arrayCast() instead for properly bounds-checked type conversion - Passing @cpp nullptr @ce to @ref ImageView constructors is deprecated and will print a warning at runtime. Use a constructor without the @p data parameter instead. - The @cpp ResourceManager::instance() @ce singleton is deprecated as it makes some use cases harder than they should be. Make your own singleton or explicitly pass a @ref ResourceManager reference around instead. - @ref Platform::BasicScreen::application() now returns a reference instead of a pointer and together with @ref Platform::BasicScreen::redraw() checks that the screen is actually added to the application instead of returning @cpp nullptr @ce (and requiring excessive error checking in user code) or, in case of @ref Platform::BasicScreen::redraw() "redraw()" silently doing the wrong thing. For backwards compatibility @ref Platform::BasicScreenedApplication is convertible to a pointer and implements @cpp operator-> @ce, but this conversion is deprecated. - @cpp Math::swizzle() @ce is deprecated, use @ref Math::gather() instead as that fits better with the new @ref Math::scatter() @subsection changelog-latest-compatibility Potential compatibility breakages, removed APIs - Configuration value parsers and writers for @ref Math types were moved to a dedicated @ref Magnum/Math/ConfigurationValue.h header in order to speed up compile times. Backwards compatibility is not provided, when using @ref Math types with @ref Corrade::Utility::Configuration or @ref Corrade::Utility::Arguments you have to include the header explicitly - @ref Audio::Extension::extensions() and @ref GL::Extension::extensions() now return a @ref Corrade::Containers::ArrayView instead of a reference to @ref std::vector in order to reduce binary bloat and compile times - Removed all aliases to @ref GL library functionality in the root namespace (and root include path) which were deprecated in 2018.04 and everything related to this change: - @cpp GL::Mesh::IndexType @ce and @cpp GL::Mesh::indexSize() @ce, use @ref GL::MeshIndexType and @ref GL::Mesh::indexTypeSize() instead - Removed @cpp Primitives::Capsule2D @ce, @cpp Primitives::Capsule3D @ce, @cpp Primitives::Circle @ce, @cpp Primitives::Crosshair2D @ce, @cpp Primitives::Crosshair3D @ce, @cpp Primitives::Cube @ce, @cpp Primitives::Cylinder @ce, @cpp Primitives::Icosphere @ce, @cpp Primitives::Line @ce, @cpp Primitives::Plane @ce, @cpp Primitives::Square @ce and @cpp Primitives::UVSphere @ce classes deprecated in 2018.04. The same functionality is available through free functions in the @ref Primitives namespace, use those instead. - Removed templated overloads of @ref GL::Buffer::data(), @ref GL::Buffer::subData() and @ref GL::Buffer::map() deprecated since 2017. Use the non-templated versions together with @ref Corrade::Containers::arrayCast(). - Removed @cpp GL::Context::DetectedDriver::AMD @ce and @cpp GL::Context::DetectedDriver::ProbablyAngle @ce aliases deprecated since 2017, use consistently-named @ref GL::Context::DetectedDriver::Amd and @ref GL::Context::DetectedDriver::Angle instead - Removed @cpp GL::CubeMapTexture::Coordinate @ce deprecated since 2016, use @ref GL::CubeMapCoordinate instead - Removed remaining @ref Platform::Sdl2Application "Platform::*Application" constructors taking @cpp nullptr @ce instead of @ref NoCreate, deprecated since 2017 - Removed compatibility code in @ref Audio::Context where @ref Audio::Context::current() would be usable with both @cpp . @ce and @cpp -> @ce, deprecated since 2017 - Removed @cpp Audio::Context::hrtfSpecifier() @ce deprecated since 2018.02. Use @ref Audio::Context::hrtfSpecifierString() instead. - Removed the `Shapes` library together with `DebugTools::ShapeRenderer`, which was a failed design experiment deprecated since version 2018.10 (see [mosra/magnum#148](https://github.com/mosra/magnum/issues/148)) - Removed the `Platform::GlutApplication` as it was based on an outdated toolkit and deprecated since version 2018.10 (see [mosra/magnum#148](https://github.com/mosra/magnum/issues/148) and [mosra/magnum#195](https://github.com/mosra/magnum/pull/195)) - In order to be compatible with both Emscripten 1.38.27 and the versions before, all Emscripten markup is now expected to have the HTML @cb{.html} @ce element identified by @cb{.css} #canvas @ce. You need to: - update your HTML markup to use @cb{.html} @ce instead of @cb{.html} @ce - in case you have a copy or a fork of the JS driver file, it needs to define @cb{.js} Module.canvas @ce as @cb{.js} document.getElementById('canvas') @ce (instead of @cb{.js} 'module' @ce) - and for CSS files, all references to @cb{.css} #module @ce need to be @cb{.css} #canvas @ce now - The `BUILD_MULTITHREADED` CMake option and `MAGNUM_BUILD_MULTITHREADED` CMake / preprocessor variable has been moved to Corrade --- you need to toggle it when building Corrade and use @ref CORRADE_BUILD_MULTITHREADED instead - @ref PixelFormat and @ref CompressedPixelFormat now reserve the zero value to indicate an invalid format, better catching accidentally forgotten initialization. Valid code shouldn't be affected by this change, but broken code that seemingly worked before might start throwing assertions now. - @ref Shaders::MeshVisualizer now asserts if its wireframe-related setters are called when the @ref Shaders::MeshVisualizer::Flag::Wireframe flag was not set, consistently with other shaders. This might cause failures in code that was calling them unnecessarily before. @section changelog-2019-01 2019.01 Released 2019-02-04, tagged as [v2019.01](https://github.com/mosra/magnum/releases/tag/v2019.01). @subsection changelog-2019-01-dependencies Dependency changes - Minimal supported GCC version is now 4.8.1, GCC 4.7 is not supported anymore. Minimal Clang version is now 3.3, since that's the first version with a complete C++11 support. See also [mosra/magnum#274](https://github.com/mosra/magnum/issues/274). - Minimal supported CMake version is now 3.1. Older versions are not supported anymore and all workarounds for them were removed.

See also [mosra/magnum#274](https://github.com/mosra/magnum/issues/274). @subsection changelog-2019-01-new New features @subsubsection changelog-2019-01-new-animation Animation library - New @ref Animation::Easing namespace with a collection of well-documented easing functions - New @ref Animation::ease(), @ref Animation::easeClamped(), @ref Animation::unpack(), @ref Animation::unpackEase() and @ref Animation::unpackEaseClamped() utilities for combining interpolators with easing functions and/or unpackers - @ref Animation::Player::resume() that acts the same as @ref Animation::Player::play() "play()" except it doesn't restart the animation from the start if it is already playing - Added @ref Animation::Player::advance(T, std::initializer_list>>) for advancing multiple players at the same time @subsubsection changelog-2019-01-new-math Math library - Support for using the @ref Math::Deg, @ref Math::Rad, @ref Math::Half, @ref Math::Color3 and @ref Math::Color4 literals with the new experimental @ref Corrade::Utility::Tweakable utility. See also @ref tweakableliterals. - New @ref Math::StrictWeakOrdering functor making it possible to use Magnum math types as keys in ordered STL containers such as @ref std::map or @ref std::set (see also [mosra/magnum#299](https://github.com/mosra/magnum/pull/299)) @subsubsection changelog-2019-01-new-platform Platform libraries - Added @ref Platform::AndroidApplication::framebufferSize(), @ref Platform::AndroidApplication::dpiScaling(), @ref Platform::AndroidApplication::ViewportEvent::dpiScaling(), @ref Platform::GlfwApplication::ViewportEvent::framebufferSize() and @ref Platform::GlfwApplication::ViewportEvent::dpiScaling() to ensure feature parity with @ref Platform::Sdl2Application - Clarified HiDPI behavior of Android apps and mentioning @ref platforms-android-apps-manifest-screen-compatibility-mode "the necessary steps" in the docs - Implemented handling of @ref Platform::AndroidApplication::viewportEvent() and documenting how to get Android to call it instead of relaunching the app from scratch - New @ref Platform::Sdl2Application::exitEvent() and @ref Platform::GlfwApplication::exitEvent() events for responding to application window close and possibility to cancel it (for example to show an exit confirmation dialog) - New @ref Platform::Sdl2Application::anyEvent() event together with @ref Platform::Sdl2Application::InputEvent::event() "event()" accessors to make it possible to access raw `SDL_Event` data @subsubsection changelog-2019-01-new-vk Vk library - Conversion between Magnum math types and math-related Vulkan types in a new @ref Magnum/Vk/Integration.h header @subsection changelog-2019-01-changes Changes and improvements @subsubsection changelog-2019-01-changes-audio Audio library - @ref Audio::Source::play(), @ref Audio::Source::pause(), @ref Audio::Source::rewind() and @ref Audio::Source::stop() now return a self-reference like all other methods for easier method chaining @subsubsection changelog-2019-01-changes-gl GL library - Added a @cpp "nv-egl-incorrect-gl11-function-pointers" @ce workaround that explicitly loads OpenGL 1.0 and 1.1 function pointers on contexts created using EGL on NVidia drivers, because there functions such as @fn_gl{GetString} behave incorrectly when linked statically. See also [mosra/magnum#308](https://github.com/mosra/magnum/pull/308). - New @ref GL::Context::State::BindScratchVao state to make external OpenGL code that's not VAO-aware working on core GL profiles (which don't allow default VAOs being used for drawing) @subsubsection changelog-2019-01-changes-platform Platform libraries - @ref Platform::Sdl2Application::swapBuffers(), "Platform::*Application::swapBuffers()" @ref Platform::Sdl2Application::swapInterval() "swapInterval() const" const, @ref Platform::Sdl2Application::setSwapInterval() "setSwapInterval()", @ref Platform::Sdl2Application::setMinimalLoopPeriod() "setMinimalLoopPeriod()" and @ref Platform::Sdl2Application::redraw() "redraw()" were changed from protected to public to allow calling them from outside @subsubsection changelog-2019-01-changes-text Text library - The @ref Text::AbstractFont and @ref Text::AbstractFontConverter plugin APIs now return @ref Corrade::Containers::Pointer instead of @ref std::unique_ptr for improved compile times @subsubsection changelog-2019-01-changes-texturetools TextureTools library - Further performance and output quality improvements for @ref TextureTools::DistanceField, making the ES2/WebGL 1 consistent with desktop and speeding up the processing to take only 60% of the time compared to before. It's now also possible to reuse the internal state for batch processing. @subsubsection changelog-2019-01-changes-trade Trade library - The @ref Trade::AbstractImporter plugin API now returns @ref Corrade::Containers::Pointer instead of @ref std::unique_ptr for improved compile times @subsection changelog-2019-01-buildsystem Build system - Experimental support for creating Android APKs directly using CMake without Gradle involved. See @ref platforms-android-apps for more information. See also [mosra/toolchains#5](https://github.com/mosra/toolchains/pull/5) and [mosra/toolchains#6](https://github.com/mosra/toolchains/pull/6). - Initial scaffolding for [Hunter](https://hunter.sh) package support (see [mosra/magnum#298](https://github.com/mosra/magnum/pull/298)) - The `package/msys` directory now contains `PKGBUILD`s for [MSYS2](https://www.msys2.org/). See @ref building-packages-msys for more information. See also [mosra/magnum#307](https://github.com/mosra/magnum/pull/307). - The `Magnum::AndroidApplication` target was missing a few dependency libraries when Magnum was used as a CMake subproject - Fixed an ambiguous overload error in @ref Text::GlyphCache when compiling this library under C++17 (see [mosra/magnum#297](https://github.com/mosra/magnum/pull/297)) - Imroved initial Emscripten setup on Windows to be more frictionless (see [mosra/toolchains#4](https://github.com/mosra/toolchains/pull/4)) - @ref DebugTools no longer unconditionally requires the @ref Trade library in case @ref Corrade::TestSuite is found. The @ref DebugTools::CompareImage documentation was updated to mention the optionality. @subsection changelog-2019-01-bugfixes Bug fixes - Fixed @ref Platform::Sdl2Application and @ref Platform::GlfwApplication to properly support the @cb{.sh} $MAGNUM_DPI_SCALING @ce environment variable as an alternative to `--magnum-dpi-scaling` command-line parameter. It was also not documented anywhere. Besides that, the default `--magnum-dpi-scaling` value should have been `default` as documented, not `virtual`. - Don't assert in DPI scaling detection in @ref Platform::Sdl2Application and @ref Platform::GlfwApplication on X11 DEs that don't create any `RESOURCE_MANAGER` (see [mosra/magnum#290](https://github.com/mosra/magnum/issues/290)) - Properly escaping log output on Emscripten @ref Platform::WindowlessEglApplication - The @ref GL::Context::States enum set was missing value combining operators - Fixed @ref Text::DistanceFieldGlyphCache internal formats on ES2 devices that support @gl_extension{EXT,texture_storage} (see [mosra/magnum#289](https://github.com/mosra/magnum/pull/289)) - @ref PixelStorage::imageHeight() and Z value of @ref PixelStorage::skip() was not properly handled on ES3 / WebGL 2 builds. @subsection changelog-2019-01-docs Documentation - Fixed various broken links (see [mosra/magnum#291](https://github.com/mosra/magnum/issues/291)) - A dedicated @ref types-thirdparty-integration section listing all provided integrations with 3rd party math APIs @subsection changelog-2019-01-deprecated Deprecated APIs - All uses of @ref std::unique_ptr in @ref Text::AbstractFont, @ref Text::AbstractFontConverter and @ref Trade::AbstractImporter are replaced with @ref Corrade::Containers::Pointer. The types are implicitly move-convertible to each other if the @ref Corrade/Containers/PointerStl.h header is included. The header is included where needed if @ref MAGNUM_BUILD_DEPRECATED is enabled. To ensure your code keeps with future versions of Magnum, either switch your code to use @ref Corrade::Containers::Pointer as well or include the @ref Corrade/Containers/PointerStl.h header explicitly. - @cpp TextureTools::distanceField() @ce is deprecated due to inefficiency of its statelessness when doing batch processing. Use the @ref TextureTools::DistanceField class instead. - @cpp Platform::GlfwApplication::KeyEvent::Key::Smicolon @ce has a typo and so is deprecated in favor of @ref Platform::GlfwApplication::KeyEvent::Key::Semicolon @subsection changelog-2019-01-compatibility Potential compatibility breakages, removed APIs - The @ref MeshTools::fullScreenTriangle() function now returns just a @ref GL::Mesh instead of @ref std::pair of a mesh and a buffer, as the buffer is now owned by the mesh. This change was not possible to be done in a backwards-compatible way. - @ref Animation::Player, @ref Audio::Listener, @ref GL::AbstractShaderProgram, @ref GL::MeshView and @ref GL::Shader APIs that take a @ref std::initializer_list of references were changed to use @ref Corrade::Containers::Reference instead of a @ref std::reference_wrapper. This change should be fully transparent to the user as the type conversion is done implicitly in both cases, but you may need to add an @cpp #include @ce where appropriate. - Removed deprecated implicit conversion @ref Corrade::Containers::Optional to @ref std::optional, deprecated in January 2018. The class now contains an *explicit* and opt-in STL compatibility, see its documentation for more information. You may need to add an @cpp #include @ce where appropriate. - Removed the `Magnum/Test/AbstractOpenGLTester.h` header that was deprecated in January 2017. Use @ref Magnum/GL/OpenGLTester.h and the @ref GL::OpenGLTester library instead. Note that the deprecated `Magnum/OpenGLTester.h` header is still present, along with all other deprecated GL-specific headers and APIs in the project root. - Removed five-argument @ref Trade::MeshData2D and six-argument @ref Trade::MeshData3D constructors that were deprecated since February 2017. Use the full six/seven-argument versions instead. - Removed @ref Platform application constructors taking @cpp nullptr @ce, deprecated in June 2016 for windowless apps and in March 2017 for windowed apps. Use constructors taking the @ref NoCreate tag instead. - Removed availability of @ref Math::Color3 and @ref Math::Color4 literals in the root namespace, deprecated since April 2016. Explicitly call @cpp using namespace Math::Literals; @ce instead. - Removed uppercase `*HSV` APIs from @ref Math::Color3 and @ref Math::Color4, deprecated since December 2016. Use the CamelCased `*Hsv` APIs instead. - Removed @cpp Math::normalize() @ce and @cpp Math::denormalize() @ce functions, deprecated since December 2016. Use @ref Math::pack() and @ref Math::unpack() instead. - Removed @cpp Platform::*Application::MouseEvent::Button::WheelUp @ce and @cpp Platform::*Application::MouseEvent::Button::WheelDown @ce, deprecated since June 2016. Use the dedicated @ref Platform::Sdl2Application::mouseScrollEvent() "mouseScrollEvent()" API instead. - Removed @cpp Platform::GlfwApplication::Configuration::WindowFlag::Resizeable @ce, deprecated since February 2017. Use @ref Platform::GlfwApplication::Configuration::WindowFlag::Resizable instead. - Removed `MAGNUM_*_LIBRARIES` and `MAGNUM_*_INCLUDE_DIRS` CMake variables, which were deprecated in favor of `Magnum::*` imported targets in February 2016. @section changelog-2018-10 2018.10 Released 2018-10-23, tagged as [v2018.10](https://github.com/mosra/magnum/releases/tag/v2018.10). @subsection changelog-2018-10-new New features @subsubsection changelog-2018-10-new-animation Animation library - New experimental @ref Animation library for keyframe-based animation playback (see [mosra/magnum#191](https://github.com/mosra/magnum/pull/191), [mosra/magnum#267](https://github.com/mosra/magnum/pull/267)) @subsubsection changelog-2018-10-new-debugtools DebugTools library - New @ref DebugTools::CompareImageFile, @ref DebugTools::CompareImageToFile and @ref DebugTools::CompareFileToImage comparators extending @ref DebugTools::CompareImage with convenient image file loading @subsubsection changelog-2018-10-new-gl GL library - Exposing @ref GL::Context::Flag::ForwardCompatible through @ref GL::Context::flags(), which was deliberately ignored before. - New @ref GL::Renderer::lineWidthRange() limit query.

See @ref GL-Mesh-buffer-ownership for more information. - @ref GL::Mesh::draw() and @ref GL::MeshView::draw() now return a reference to self to make method-chained draws (for example using a different shader) possible as well - The @ref GL::BufferUsage parameter in @ref GL::Buffer::setData() is now optional, defaults to @ref GL::BufferUsage::StaticDraw @subsubsection changelog-2018-10-changes-math Math library - All assertions in the @ref Math namespace now helpfully print the offending value that caused the assert for easier debugging - @ref Math::Matrix3::rotation() const and @ref Math::Matrix4::rotation() const now allow non-uniform scaling, but expect the roation/scaling part to be orthogonal after normalization - @ref Math::angle(), @ref Math::Vector::lengthInverted(), @ref Math::Vector::normalized(), @ref Math::Vector::resized(), @ref Math::Vector::projected(), @ref Math::Vector::projectedOntoNormalized() and @ref Math::Vector2::aspectRatio() are now enabled only for floating-point types to avoid errors when using these functions accidentally on integral vectors (see [mosra/magnum#251](https://github.com/mosra/magnum/issues/251)) @subsubsection changelog-2018-10-changes-meshtools MeshTools library - @ref MeshTools::compile() API got simplified to make use of the new buffer ownership feature of @ref GL::Mesh - @ref MeshTools::compile() learned to handle vertex color attributes as well (see [mosra/magnum#284](https://github.com/mosra/magnum/pull/284)) @subsubsection changelog-2018-10-changes-platform Platform libraries - @ref Platform::Sdl2Application::viewportEvent() "Platform::*Application::viewportEvent()" now gets all information needed for DPI-aware rendering instead of just a framebuffer size --- now also window size and the DPI scaling value - Overhauled the builtin @ref platforms-html5 "Emscripten" HTML markup and styling for HTML5/WebGL apps: - the builtin style now matches the dark theme of the Magnum website - canvas is responsively sized and preserves aspect ratio when scaled down - when the app aborts, a helpful message is printed instead of everything getting stuck - it's possible to override the default canvas size and aspect ratio, see @ref platforms-html5-layout - documentation explaining quirks of event handling, see @ref platforms-html5-events - @ref Platform::GlfwApplication now behaves the same as @ref Platform::Sdl2Application when creating an OpenGL context: first it attempts to create a forward-compatible core OpenGL 3.2+ context and if that fails, falls back to 2.1+ compatibility context. The @cpp "no-forward-compatible-core-context" @ce workaround is implemented as well, see @ref opengl-workarounds for more information. - @ref Platform::GlfwApplication no longer stores a needless global window pointer - @ref Platform::GlfwApplication now loads modifiers for mouse move and mouse scroll events lazily, only when needed - @ref Platform::BasicScreen::viewportEvent() "Platform::Screen::viewportEvent()" is no longer pure virtual to be consistent with all `*Application` implementations - @ref Platform::Sdl2Application now defaults to the actual canvas size on @ref CORRADE_TARGET_EMSCRIPTEN "Emscripten", instead of hardcoded @cpp {640, 480} @ce - @ref Platform::Sdl2Application::Configuration::WindowFlags values that make no sense on Emscripten are not available there anymore - When using SDL 2.0.8 and newer, @ref Platform::Sdl2Application no longer attempts to disable compositing on Linux.

See @ref opengl-workarounds for more information. @subsubsection changelog-2018-10-changes-shaders Shaders library - All shaders now have reasonable default values for uniforms in order to further simplify and remove friction from quick prototyping use cases - @ref Shaders::Flat::bindTexture(), @ref Shaders::Phong::bindAmbientTexture(), @ref Shaders::Phong::bindDiffuseTexture(), @ref Shaders::Phong::bindSpecularTexture() and @ref Shaders::Phong::bindTextures() now assert that the shader was created with the corresponding flag enabled to prevent accidental "black screen of death" errors. - Ambient color in untextured @ref Shaders::Phong now defaults to @cpp 0x00000000_rgbaf @ce in order to support alpha-masked drawing out of the box @subsubsection changelog-2018-10-changes-texturetools TextureTools library - Fixed @ref TextureTools::distanceField() to not require more than 8 texture units, which is the limit on all iOS ES2 contexts, independently on the device (ES3 contexts have 16). @subsubsection changelog-2018-10-changes-trade Trade library - @ref Trade::PhongMaterialData now contains well-defined color values instead of random memory after construction @subsection changelog-2018-10-buildsystem Build system - There's now a PPA for Ubuntu packages. See @ref building-packages-deb for more information. See also [mosra/magnum#248](https://github.com/mosra/magnum/issues/248) and [mosra/magnum#249](https://github.com/mosra/magnum/pull/249). - Fixed various issues preventing to build and use the base libraries with OpenGL support disabled (see [mosra/magnum#255](https://github.com/mosra/magnum/pull/255)) - Magnum now links to GLVND on Linux instead of the old libGL ABI if using CMake 3.11 and newer - Using official Apple OpenGL include paths on iOS (see [mosra/magnum#253](https://github.com/mosra/magnum/pull/253)) - @ref cmake "FindMagnum.cmake" now allows to use the @ref DebugTools library even if some of its optional dependencies are not compiled in - `FindSDL2.cmake` now properly links to `dl` and `pthread` libraries when using a static build of SDL2 on Linux - `FindSDL2.cmake` is now able to properly find a debug build of SDL, which enables Vcpkg to properly copy all dependency DLLs on Windows (see [mosra/magnum-examples#42](https://github.com/mosra/magnum-examples/issues/42), [mosra/magnum-examples#45](https://github.com/mosra/magnum-examples/pull/45)) - `FindGLFW.cmake` is now preferring GLFW CMake config file to pick up the imported target, if available (see [mosra/magnum#194](https://github.com/mosra/magnum/pull/194)) - `FindMagnum.cmake` now provides full paths to application JS/CSS files on @ref platforms-html5 "Emscripten" builds through new `MAGNUM_EMSCRIPTENAPPLICATION_JS`, `MAGNUM_WINDOWLESSEMSCRIPTENAPPLICATION_JS` and `MAGNUM_WEBAPPLICATION_CSS` CMake variables. These files are now installed unconditionally even if no `Platform::*Application` library is built to allow them to be used with third-party application implementations. - @ref Trade::ObjImporter "ObjImporter" didn't work with CMake subprojects due to an embarrassing typo (see [mosra/magnum#259](https://github.com/mosra/magnum/issues/259)) - @ref Audio::AnyImporter "AnyAudioImporter", @ref Trade::AnyImageConverter "AnyImageConverter", @ref Trade::AnyImageImporter "AnyImageImporter" and @ref Trade::AnySceneImporter "AnySceneImporter" plugins were not correctly updated for subproject support after moving them out of the `magnum-plugins` repository - Improved out-of-the-box behavior with Emscripten toolchains (see [mosra/magnum#283](https://github.com/mosra/magnum/issues/283)) @subsection changelog-2018-10-bugfixes Bug fixes - MSVC 15.8 (released on Aug 14, 2018) has a regression causing the compiler to crash with an ICE (C1001) on @ref Math::Color4 constructors that have a default alpha parameter. This is only only when the `/permissive-` flag is specified (which is done by default for projects created directly using Visual Studio but not for projects using CMake). This has been worked around, but can't be guaranteed it was the only case. In case you're experiencing a similar issue somewhere else, please try to disable the `/permissive-` flag first. - An assert was firing during @ref Platform::GlfwApplication initialization due to a pointer not being properly initialized after the @ref Platform::GlfwApplication::GLConfiguration "GLConfiguration" rework in 2018.04 (see [mosra/magnum#246](https://github.com/mosra/magnum/pull/246), [mosra/magnum#247](https://github.com/mosra/magnum/issue/247)) - Vertex attribute divisor in @ref GL::Mesh::addVertexBufferInstanced() was not properly cleaned up after when @gl_extension{ARB,vertex_array_object} was disabled, causing subsequent draws to misbehave - Fixed @ref Shaders::DistanceFieldVector and @ref Shaders::Vector to be properly movable - Restored backwards compatibility to the templated @ref GL::Buffer::map() overload --- it was not possible to call it with @cpp void @ce template parameter - @gl_extension{ARB,direct_state_access} versions of @ref GL::Framebuffer::clearColor(), @ref GL::Framebuffer::clearDepth(), @ref GL::Framebuffer::clearStencil() and @ref GL::Framebuffer::clearDepthStencil() were binding the framebuffer for drawing, which was completely unnecessary - Deprecation status of GL-specific values of the generic @ref MeshPrimitive enum was not properly reflected in the documentation - @ref Platform::GlfwApplication::InputEvent::Modifier::Super is properly reported for both left and right modifier (Windows/⌘) key instead of just the right one - @ref Platform::GlfwApplication::exec() now asserts instead of crashing if the constructor fails to create a window (see [mosra/magnum#192](https://github.com/mosra/magnum/issues/192), [mosra/magnum#272](https://github.com/mosra/magnum/pull/272)) - @ref Platform::GlfwApplication::GLConfiguration::isSrgbCapable() has now a proper documented default value instead of being left uninitialized. - @ref Math::sclerp() was not properly interpolating the translation if rotation was the same on both sides - Improved @ref TextureTools::distanceField() to work better on shader compilers that have problems compiling nested loops (WebGL implementations, some ES2 devices) - @ref SceneGraph::AbstractObject::addFeature() and @ref SceneGraph::Object::addChild() were not properly forwarding reference arguments @subsection changelog-2018-10-docs Documentation - New @ref custom-buildsystems page listing the most important things to keep in mind when using Magnum with custom buildsystems. See also [mosra/magnum#268](https://github.com/mosra/magnum/pull/268). - Compiled code snippets for @ref Audio and @ref SceneGraph libraries, fixing cases where outdated or plain wrong API constructs were mentioned - Extended documentation for @ref Math::Matrix3::rotation(), @ref Math::Matrix4::rotation() and related accessors, explaining use cases and caveats - Reworked documentation of @ref Math::Algorithms, adding math equations and usage examples to all functions - Improved documentation of @ref Math::Constants, showing useful identities for each - The @ref scenegraph documentation was proofread and extended with a section covering basics with visual diagrams. - Explicitly mentioning copy/move constructibility for all classes with non-trivial construction - Improved Vcpkg build instructions (see [mosra/magnum#271](https://github.com/mosra/magnum/pull/271), [mosra/magnum#273](https://github.com/mosra/magnum/pull/273)) - Website styling got out of sync with generated Doxygen documentation, causing search icon to either disappear on some browsers or be extremely oversized on others (see [mosra/magnum#260](https://github.com/mosra/magnum/issues/260), [mosra/magnum#261](https://github.com/mosra/magnum/issues/261)) - Documentation of @ref Primitives and @ref Shaders namespaces now has proper sRGB and HiDPi renderings of all primitives and shaders - Various other fixes and updates (see [mosra/magnum#281](https://github.com/mosra/magnum/pull/281)) @subsection changelog-2018-10-deprecated Deprecated APIs - The `Shapes` library is a failed design experiment and is scheduled for removal in a future release, together with `DebugTools::ShapeRenderer`. Related geometry algorithms were moved to @ref Math::Distance and @ref Math::Intersection; if you need a full-fledged physics library, please have look at [Bullet](https://bulletphysics.org), which has Magnum integration in @ref BulletIntegration, or at [Box2D](https://box2d.org/), which has a @ref examples-box2d "Magnum example" as well. - `Platform::GlutApplication` is based on an outdated toolkit and thus scheduled for removal in a future release. Please consider switching to @ref Platform::Sdl2Application or @ref Platform::GlfwApplication as soon as possible. - `Platform::*Application::viewportEvent(const Vector2i&)` is deprecated because it doesn't provide all information needed for DPI-aware rendering. Override the @ref Platform::Sdl2Application::viewportEvent(ViewportEvent&) "viewportEvent(ViewportEvent&)" function instead. - `Platform::Sdl2Application::Configuration::WindowFlags::AllowHighDpi` is deprecated and has no effect as it is now passed implicitly on platforms that need it - `Math::Geometry`, `Math::Geometry::Distance` and `Math::Geometry::Intersection` namespaces are deprecated for being too deeply nested, use @ref Math::Distance and @ref Math::Intersection instead - `Math::Geometry::Intersection::boxFrustum()` is deprecated, use @ref Math::Intersection::rangeFrustum() instead - @ref Math::Intersection::planeLine() taking a separate plane normal and position is deprecated, use @ref Math::planeEquation() and the overload taking a plane equation as @ref Math::Vector4 instead - @ref Audio::PlayableGroup::setClean() is deprecated in favor of @ref Audio::Listener::update(), as that one is a feature superset with clearer naming - @ref MeshTools::compile() taking a @ref GL::BufferUsage and returning a tuple was deprecated, use the simpler version taking just @ref Trade::MeshData2D / @ref Trade::MeshData3D and directly returning a @ref GL::Mesh instead - `Shaders::VertexColor::Color` is deprecated, use the direct @ref Shaders::VertexColor::Color3 or @ref Shaders::VertexColor::Color4 alternatives instead - @ref Trade::AbstractMaterialData constructor taking just two parameters and @ref Trade::PhongMaterialData constructor taking three parameters are deprecated, use @ref Trade::AbstractMaterialData::AbstractMaterialData(MaterialType, Flags, MaterialAlphaMode, Float, const void*) and @ref Trade::PhongMaterialData::PhongMaterialData(Flags, MaterialAlphaMode, Float, Float, const void*) instead - @ref Trade::CameraData constructor not taking an explicit type enum is deprecated, use @ref Trade::CameraData::CameraData(CameraType, Rad, Float, Float, Float, const void*) instead - @cpp GL::*Texture::setSRGBDecode() @ce, @cpp GL::Renderer::Feature::FramebufferSRGB @ce, @cpp Platform::*Application::GLConfiguration::setSRGBCapable() @ce and @cpp Platform::*Application::GLConfiguration::isSRGBCapable() @ce is deprecated, use @ref GL::Texture::setSrgbDecode() "GL::*Texture::setSrgbDecode()", @ref GL::Renderer::Feature::FramebufferSrgb, @ref Platform::Sdl2Application::GLConfiguration::setSrgbCapable() "Platform::*Application::GLConfiguration::setSrgbCapable()" and @ref Platform::Sdl2Application::GLConfiguration::isSrgbCapable() "Platform::*Application::GLConfiguration::isSrgbCapable()" instead as it has consistent naming with @ref Math::Color3 "Math::Color" APIs @subsection changelog-2018-10-compatibility Potential compatibility breakages, removed APIs - The `Shapes` library is not built by default anymore due to its deprecated status - @ref Audio::Playable is now by default omnidirectional instead of having source in direction of negative Z axis (the direction has effect only when setting inner and outer cone properties of @ref Audio::Source). - @ref Math::Matrix3::rotation() const and @ref Math::Matrix4::rotation() const now allow non-uniform scaling, but expect the roation/scaling part to be orthogonal after normalization (before it required uniform scaling but not orthogonal axes) --- this might cause imprecise data that were previously working to fail with an assertion. See the new @ref Math::Matrix3::rotationShear() and @ref Math::Matrix4::rotationShear() accessors for a possible solution. - Since one-dimensional @ref Math::Range is now used on many new places such as the @ref Animation library, its underlying type is just @cpp T @ce instead of @ref Math::Vector "Math::Vector<1, T>" to make it easier to use. This may break rare existing code that was using one-dimensional ranges or generic code that's always expecting a vector type. See @ref Math-Range-generic for possible solutions. - @ref SceneGraph::Camera::setViewport() and @ref SceneGraph::Camera::draw() are no longer @cpp virtual @ce functions. If you need to override their functionality, simply call the subclass implementation directly instead of calling it through a @ref SceneGraph::Camera. - @ref Shaders::Flat::bindTexture(), @ref Shaders::Phong::bindAmbientTexture(), @ref Shaders::Phong::bindDiffuseTexture(), @ref Shaders::Phong::bindSpecularTexture() and @ref Shaders::Phong::bindTextures() now assert that the shader was created with the corresponding flag enabled to prevent accidental "black screen of death" errors. This might cause your application to abort if it was calling these functions when not needed. - Ambient color in untextured @ref Shaders::Phong now defaults to @cpp 0x00000000_rgbaf @ce in order to support alpha-masked drawing out of the box. This may break code that assumed the alpha channel being opaque by default. - @ref Trade::PhongMaterialData::ambientColor(), @ref Trade::PhongMaterialData::diffuseColor() "diffuseColor()" and @ref Trade::PhongMaterialData::specularColor() "specularColor()" now return @ref Color4 instead of @ref Color3 - Applications now expose GL context forward compatibility as an enabled-by-default context flag. Calling @ref Platform::Sdl2Application::GLConfiguration::setFlags() "Platform::*Application::GLConfiguration::setFlags()" (and similarly on windowless apps) will reset that flag, use @ref Platform::Sdl2Application::GLConfiguration::addFlags() "Platform::*Application::GLConfiguration::addFlags()" (And similarly on windowless apps) to preserve the enabled-by-default flags. @section changelog-2018-04 2018.04 Released 2018-05-01, tagged as [v2018.04](https://github.com/mosra/magnum/releases/tag/v2018.04). @subsection changelog-2018-04-dependencies Dependency changes - Building for Android now requires CMake 3.7 with builtin Android crosscompilation support, the old toolchains were removed. Only the Clang and libc++ toolchain is now supported, support for GCC and libstdc++ was dropped, as it was still missing some important C++11 functionality. See @ref building-cross-android for more information. @subsection changelog-2018-04-new New features - New @ref PixelFormat / @ref CompressedPixelFormat enums containing generic API-independent pixel formats, together with @ref pixelSize(), @ref pixelFormatWrap() / @ref pixelFormatUnwrap(), @ref compressedPixelFormatWrap() / @ref compressedPixelFormatUnwrap() and @ref isPixelFormatImplementationSpecific() / @ref isCompressedPixelFormatImplementationSpecific() utilities now used by @ref Image / @ref CompressedImage and @ref ImageView / @ref CompressedImageView instead of the GL-specific formats - New @ref MeshPrimitive and @ref MeshIndexType enums containing generic API-independent mesh primitive types and index types, together with @ref meshIndexTypeSize() utilities - New @ref SamplerFilter, @ref SamplerMipmap and @ref SamplerWrapping enums containing generic API-independent texture sampler modes @subsubsection changelog-2018-04-new-math Math library - Added @ref Math::isInf(), @ref Math::isNan() @subsubsection changelog-2018-04-new-gl GL library - A new library that now contains wrappers for the OpenGL family of graphics APIs, separated from the core Magnum library (see [mosra/magnum#233](https://github.com/mosra/magnum/pull/233)) - New @ref GL::hasPixelFormat(), @ref GL::pixelFormat(), @ref GL::pixelType(), @ref GL::hasCompressedPixelFormat(), @ref compressedPixelFormat() utilities for converting generic @ref PixelFormat / @ref CompressedPixelFormat to GL-specific @ref GL::PixelFormat, @ref GL::PixelType and @ref GL::CompressedPixelFormat values. The @ref GL::BufferImage and @ref GL::CompressedBufferImage classes now have overloads accepting both types. - New @ref GL::meshPrimitive() and @ref GL::meshIndexType() utilities for converting generic @ref MeshPrimitive and @ref MeshIndexType to GL-specific @ref GL::MeshPrimitive and @ref GL::MeshIndexType values. The @ref GL::Mesh class now has overloads accepting both types. - New @ref GL::Mesh::indexType() and @ref GL::MeshView::mesh() getters - New @ref GL::samplerFilter(), @ref GL::samplerMipmap() and @ref GL::samplerWrapping() utilities for converting generic @ref SamplerFilter, @ref SamplerMipmap and @ref SamplerWrapping to G L-specific @ref GL::SamplerFilter, @ref GL::SamplerMipmap and @ref GL::SamplerWrapping values. All texture classes now have overloads accepting both types. - Initial support for OpenGL ES 3.2 and OpenGL 4.6 (see [mosra/magnum#224](https://github.com/mosra/magnum/issues/224), [mosra/magnum#231](https://github.com/mosra/magnum/pull/231)) - New OpenGL extension support: - @gl_extension{ARB,texture_filter_anisotropic} - @gl_extension{OES,texture_float}, @gl_extension2{OES,texture_half_float,OES_texture_float} - @gl_extension{EXT,color_buffer_float}, @gl_extension2{EXT,color_buffer_half_float,EXT_color_buffer_half_float} and their WebGL counterparts @webgl_extension{EXT,color_buffer_half_float}, @webgl_extension{WEBGL,color_buffer_float}, @webgl_extension{EXT,color_buffer_float} - Ported @ref GL::OpenGLTester to WebGL @subsubsection changelog-2018-04-new-platform Platform libraries - Ability to create @ref Platform::Sdl2Application and @ref Platform::GlfwApplication classes without implicitly created OpenGL context by passing @ref Platform::Sdl2Application::Configuration::WindowFlag::Contextless "Configuration::WindowFlag::Contextless" to them. These two can be now also built completely without the GL library. - Added @ref Platform::AndroidApplication::windowSize() - Added @ref Platform::AndroidApplication::nativeActivity() to access underlying `ANativeActivity` structure for calling various Android APIs @subsubsection changelog-2018-04-new-primitives Primitives library - New @ref Primitives::circle3DSolid(), @ref Primitives::circle3DWireframe(), @ref Primitives::coneSolid(), @ref Primitives::coneWireframe(), @ref Primitives::grid3DSolid() and @ref Primitives::grid3DWireframe() primitives @subsubsection changelog-2018-04-new-trade Trade library - Debug output operator for @ref Trade::PhongMaterialData::Flag and @ref Trade::PhongMaterialData::Flags @subsection changelog-2018-04-changes Changes and improvements - The @ref CompressedPixelStorage class and related APIs are now available on all targets including OpenGL ES and WebGL, however at the moment, until a compatibility code path is implemented, the @ref GL library expects that all parameters are at their defaults. @subsubsection changelog-2018-04-changes-debugtools DebugTools library - @ref DebugTools::textureSubImage() now accepts both GL-specific @ref GL::PixelFormat / @ref GL::PixelType combination and the generic @ref PixelFormat enum - @ref DebugTools::CompareImage now accepts generic @ref PixelFormat on input instead of GL-specific @ref GL::PixelFormat / @ref GL::PixelType @subsubsection changelog-2018-04-changes-gl GL library - The @ref GL::Mesh::indexTypeSize() and @ref GL::MeshView::setIndexRange() now expect that the mesh is indexed (instead of silently not doing anything) @subsubsection changelog-2018-04-changes-text Text library - The @ref Text::GlyphCache now unconditionally uses @ref GL::TextureFormat::Luminance on ES2 and WebGL 1, instead of trying @ref GL::TextureFormat::Red there first. That's done for consistency with @ref GL::pixelFormat(), which unconditionally returns @ref GL::PixelFormat::Luminance for @ref PixelFormat::R8Unorm. @subsubsection changelog-2018-04-changes-platform Platform libraries - Separated @ref Platform::Sdl2Application::Configuration "Platform::*Application::Configuration" into @ref Platform::Sdl2Application::Configuration "Configuration" and @ref Platform::Sdl2Application::GLConfiguration "GLConfiguration" to allow creation of non-GL application instances in the future @subsubsection changelog-2018-04-changes-plugins Plugins - @ref Trade::TgaImporter "TgaImporter" and @ref Trade::TgaImageConverter "TgaImageConverter" plugins now operate on the generic @ref PixelFormat instead of GL-specific @ref GL::PixelFormat / @ref GL::PixelType - @ref Trade::AnySceneImporter "AnySceneImporter" now uses `GlbImporter` for loading binary glTF files instead of proxying them to `GltfImporter` plugins @subsection changelog-2018-04-buildsystem Build system - The core @ref Magnum library is not depending on OpenGL anymore, all GL-related APIs are now part of a new @ref GL library - @ref Primitives and @ref Trade libraries do not depend on OpenGL anymore - @ref DebugTools, @ref MeshTools and @ref TextureTools have only an optional dependency on the @ref GL library, controlled with `TARGET_GL` CMake option - All plugin interfaces now implement @ref Corrade::PluginManager::AbstractPlugin::pluginSearchPaths() "pluginSearchPaths()" for plugin directory autodetection --- you no longer need to specify the plugin directory explicitly when loading plugins. See @ref plugins-loading for more information. See also [mosra/magnum#235](https://github.com/mosra/magnum/issues/235). - Plugins now provide an automatic means of static plugin import via CMake targets, no need to call @ref CORRADE_PLUGIN_IMPORT() implicitly anymore. For this to work, you just need to update local copies of all Find modules. See @ref plugins-static for more information. - The @ref Audio::AnyImporter "AnyAudioImporter", @ref Trade::AnyImageConverter "AnyImageConverter", @ref Trade::AnyImageImporter "AnyImageImporter" and @ref Trade::AnySceneImporter "AnySceneImporter" plugins were moved from the plugins repository to the core Magnum repository. If you are using them statically via CMake, you need to update your copies of `FindMagnum.cmake` and `FindMagnumPlugins.cmake` modules. See @ref building and @ref cmake for more information. - The @ref Trade namespace is now a separate library, allowing to use core Magnum functionality without @ref Corrade::PluginManager - Suppressed a MSVC warning in @ref MeshTools::interleave() (see [mosra/magnum#238](https://github.com/mosra/magnum/issues/238)) - Fixed Vcpkg packages to properly copy all plugin and their dependencies along the executable (see [mosra/magnum#235](https://github.com/mosra/magnum/issues/235), [mosra/magnum-examples#41](https://github.com/mosra/magnum-examples/issues/41)) - Stable version of Magnum is now available as a binary package in the ArchLinux `[community]` repo - Homebrew macOS packages were updated to install the stable version by default - Fixed the Debian package after introducing `SOVERSION` to all libraries (see [mosra/magnum#237](https://github.com/mosra/magnum/issues/237)) - Fixed the Debian package to not include a revision. While just a warning on Ubuntu, it's a hard error on Debian. (See [mosra/corrade#44](https://github.com/mosra/corrade/issues/44).) @subsection changelog-2018-04-bugfixes Bug fixes - Engine startup info was not properly printed to Android log since introducing the `--magnum-log` option in version 2018.02 - Dropped Google Closure Compiler from Emscripten toolchains, it was bringing more harm than good (see [mosra/magnum#211](https://github.com/mosra/magnum/issues/211)) - Working around Emscripten issue where `-s USE_PTHREADS=1` would cause all shader sources containing Unicode characters to be truncated to empty strings. See the @cpp "emscripten-pthreads-broken-unicode-shader-sources" @ce workaround description and [mosra/magnum#239](https://github.com/mosra/magnum/issues/239) for details. - @ref GL::Attribute::DataType::HalfFloat was not available on WebGL 2 by mistake - A wrong code path for @ref GL::Framebuffer::checkStatus() was selected on WebGL 1 by mistake - Fixed `MAGNUM_PLUGINS_DIR` variables to contain proper absolute location by default again. @subsection changelog-2018-04-deprecated Deprecated APIs - All GL-related headers and APIs from the root `Magnum/` directory and @ref Magnum namespace were moved to the `Magnum/GL/` directory and @ref Magnum::GL namespace. See their documentation for information about particular files, classes, enums, typedefs, values and functions. - The `MAGNUM_ASSERT_VERSION_SUPPORTED()`, `MAGNUM_ASSERT_EXTENSION_SUPPORTED()` and `MAGNUM_VERIFY_NO_ERROR()` macros are deprecated, use @ref MAGNUM_ASSERT_GL_VERSION_SUPPORTED(), @ref MAGNUM_ASSERT_GL_EXTENSION_SUPPORTED() and @ref MAGNUM_VERIFY_NO_GL_ERROR() instead - The `Platform::Context` class is deprecated, use @ref Platform::GLContext instead - `Platform::*Application::createContext()` and `Platform::*Application::tryCreateContext()` functions are deprecated for being too GL-specific, use @ref Platform::Sdl2Application::create() "create()" and @ref Platform::Sdl2Application::tryCreate() "tryCreate()" instead - The `Extensions::GL` namespace is deprecated, use @ref GL::Extensions instead - The @ref PixelFormat and @ref CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or @ref GL::PixelFormat (together with @ref GL::PixelType) and @ref GL::CompressedPixelFormat instead. - `PixelStorage::pixelSize()` was deprecated, use @ref GL::pixelSize() or @ref Magnum::pixelSize() instead - `PixelStorage::dataProperties(GL::PixelFormat, GL::PixelSize, const Vector3i&)` was deprecated for being too GL-specific, use @ref PixelStorage::dataProperties(std::size_t, const Vector3i&) const together with @ref GL::pixelSize() instead - `Image*::type()` functions are deprecated as these are too GL-specific. The second format specifier is now available through @ref Image::formatExtra(), @ref ImageView::formatExtra() and @ref Trade::ImageData::formatExtra() - `Audio::Buffer::Format` is deprecated, use `Audio::BufferFormat` instead - `setData()` functions in the @ref Image and @ref CompressedImage classes are deprecated because they don't offer anything extra over simple move-assignment of a new instance. - The @ref MeshPrimitive enum now contains generic API-independent values. The additional GL-specific types are present there, but marked as deprecated. Use the GL-specific @ref GL::MeshPrimitive enum instead. - THe `GL::Mesh::IndexType` enum and the `Mesh::indexSize(MeshIndexType)` function is deprecated, use @ref Magnum::MeshIndexType / @ref GL::MeshIndexType and @ref meshIndexTypeSize() instead - The `GL::Mesh::indexSize()` function is deprecated, use @ref GL::Mesh::indexTypeSize() instead - The `Sampler` class and the `Sampler::Filter`, `Sampler::Mipmap`, `Sampler::Wrapping`, `Sampler::CompareMode`, `Sampler::CompareFunction` and `Sampler::DepthStencilMode` enums are deprecated, use @ref GL::Sampler, @ref SamplerFilter / @ref GL::SamplerFilter, @ref SamplerMipmap / @ref GL::SamplerMipmap, @ref SamplerWrapping / @ref GL::SamplerWrapping, @ref GL::SamplerCompareMode, @ref GL::SamplerCompareFunction and @ref GL::SamplerDepthStencilMode instead - Class @cpp Primitives::Capsule2D @ce and @cpp Primitives::Capsule3D @ce is deprecated, use @ref Primitives::capsule2DWireframe(), @ref Primitives::capsule3DSolid() and @ref Primitives::capsule3DWireframe() free functions instead - Class @cpp Primitives::Circle @ce is deprecated, use @ref Primitives::circle2DSolid() and @ref Primitives::circle2DWireframe() instead - Class @cpp Primitives::Crosshair2D @ce and @cpp Primitives::Crosshair3D @ce is deprecated, use @ref Primitives::crosshair2D() and @ref Primitives::crosshair3D() free function instead - Class @cpp Primitives::Cube @ce is deprecated, use @ref Primitives::cubeSolid(), @ref Primitives::cubeSolidStrip() and @ref Primitives::cubeWireframe() free functions instead - Class @cpp Primitives::Cylinder @ce is deprecated, use @ref Primitives::cylinderSolid(), @ref Primitives::cylinderWireframe() free functions instead - Class @cpp Primitives::Icosphere @ce is deprecated, use the @ref Primitives::icosphereSolid() free function instead - Class @cpp Primitives::Line @ce is deprecated, use the @ref Primitives::line2D() and @ref Primitives::line3D() free functions instead - Class @cpp Primitives::Plane @ce is deprecated, use @ref Primitives::planeSolid() and @ref Primitives::planeWireframe() free functions instead - Class @cpp Primitives::Square @ce is deprecated, use @ref Primitives::squareSolid() and @ref Primitives::squareWireframe() free functions instead - Class @cpp Primitives::UVSphere @ce is deprecated, use @ref Primitives::uvSphereSolid() and @ref Primitives::uvSphereWireframe() free functions instead - @cpp Shaders::*Vector::setVectorTexture() @ce, @cpp Shaders::Flat::setTexture() @ce, @cpp Shaders::Phong::setAmbientTexture() @ce, @cpp Shaders::Phong::setDiffuseTexture() @ce, @cpp Shaders::Phong::setSpecularTexture() @ce and @cpp Shaders::Phong::setTextures() @ce are deprecated because texture binding (a global state) is confused there with uniform setup (a shader-local state). That can lead to accidental state mismatches where a texture is forgotten to be rebound. Use @ref Shaders::AbstractVector::bindVectorTexture() "Shaders::*Vector::bindVectorTexture()", @ref Shaders::Flat::bindTexture(), @ref Shaders::Phong::bindAmbientTexture(), @ref Shaders::Phong::bindDiffuseTexture(), @ref Shaders::Phong::bindSpecularTexture() and @ref Shaders::Phong::bindTextures() instead. @subsection changelog-2018-04-compatibility Potential compatibility breakages, removed APIs - Code that was previously linking just to the core @ref Magnum library may now need to explicitly link to the @ref Magnum::Trade and @ref Magnum::GL libraries as well. If using CMake, these dependencies might get linked in transitively from other libraries, but that doesn't handle all cases. Due to the complexity of this change, no backwards compatibility is provided. - The `magnum-info` utility was renamed to @ref magnum-gl-info. No backwards compatibility symlinks or aliases are provided. - The `Magnum::Context` target alias was renamed to `Magnum::GLContext`. No backwards compatibility aliases are provided. - @ref PixelStorage::dataProperties(), @ref Image::dataProperties(), @ref ImageView::dataProperties(), @ref Trade::ImageData::dataProperties(), and @ref GL::BufferImage::dataProperties() now return just a pair of two values, as the third value is now accessible directly through @ref Image::pixelSize() "*Image::pixelSize()" and no longer calculated on-demand - @ref CompressedPixelStorage::dataProperties(), @ref CompressedImage::dataProperties(), @ref CompressedImageView::dataProperties() and @ref GL::CompressedBufferImage::dataProperties() now return just a pair of two values, as the third value is accessible directly through @ref CompressedPixelStorage::compressedBlockDataSize() - @ref ImageView and @ref CompressedImageView methods are no longer @cpp constexpr @ce. It might be possible to have them @cpp constexpr @ce in C++14, but the resulting increase in maintenance costs and compile times is not worth it. - `PixelFormat` has been moved verbatim to @ref GL::PixelFormat and there's a new @ref Magnum::PixelFormat enum for generic pixel formats. It contains (deprecated) @ref GL::PixelFormat values for covering most of backwards compatibility, but code that relies on these two types being the same may break. In particular, @ref GL::BufferImage::format() now returns @ref GL::PixelFormat instead of @ref Magnum::PixelFormat, code depending on the return type being implicitly convertible to @ref Magnum::PixelFormat may break. In all other cases, @ref Image::format() "Image*::format()" returns @ref Magnum::PixelFormat. - `CompressedPixelFormat` has been moved verbatim to @ref GL::CompressedPixelFormat and there's a new @ref Magnum::CompressedPixelFormat enum for generic pixel formats. It contains (deprecated) @ref GL::CompressedPixelFormat values for covering most of backwards compatibility, but code that relies on these two types being the same may break. In particular, @ref GL::CompressedBufferImage::format() now returns @ref GL::CompressedPixelFormat instead of @ref Magnum::CompressedPixelFormat, code depending on the return type being implicitly convertible to @ref Magnum::CompressedPixelFormat may break. In all other cases, @ref CompressedImage::format() "CompressedImage*::format()" returns @ref Magnum::CompressedPixelFormat. - `MeshPrimitive` has been moved verbatim to @ref GL::MeshPrimitive and there's a new @ref Magnum::MeshPrimitive enum for generic primitive types. It contains (deprecated) additional @ref GL::MeshPrimitive values for covering most of backwards compatibility, but code that relies on these two types being the same (or have values that match GL enums) may break. In particular, @ref GL::Mesh::primitive() now returns @ref GL::MeshPrimitive instead of @ref Magnum::MeshPrimitive, code depending on the return type being implicitly convertible to @ref Magnum::MeshPrimitive may break. IN all other cases, @ref Trade::MeshData2D::primitive() "Trade::MeshData*D::primitive()" etc. returns @ref Magnum::MeshPrimitive. - Configuration value reader/writers are now for only @ref Magnum::MeshPrimitive and @ref Magnum::MeshIndexType, not for @ref GL::MeshPrimitive or @ref GL::MeshIndexType - @ref DebugTools::CompareImage no longer accepts GL-specific pixel formats, only the non-deprecated values from the generic @ref PixelFormat enum - The @ref Trade::TgaImageConverter "TgaImageConverter" plugin no longer accepts GL-specific pixel formats, only the non-deprecated values from the generic @ref PixelFormat enum - The @ref Image::pixelSize(), @ref ImageView::pixelSize(), @ref Trade::ImageData::pixelSize() and @ref GL::BufferImage::pixelSize() functions now return @ref UnsignedInt instead of @cpp std::size_t @ce. - Removed `PixelStorage::setSwapBytes()`, as every Magnum API dealing with images basically only asserted that it's not set. Use @ref Corrade::Utility::Endianness instead. - Removed the @cpp Buffer::Usage @ce enum that was deprecated in 2014.01, use the global @ref GL::BufferUsage enum instead - Removed the `Magnum/Query.h` header that was deprecated in 2015.05, use one of `Magnum/PrimitiveQuery.h`, `Magnum/SampleQuery.h` or `Magnum/TimeQuery.h` instead - Removed ability to use @ref GL::Buffer::Target as constructor or @ref GL::Buffer::setTargetHint() parameter that was deprecated in 2015.05, use @ref GL::Buffer::TargetHint instead - Removed the @cpp SceneGraph::TransformationType @ce enum that was deprecated in 2015.05, use separate `()` and `Local()` variants instead - Removed @cpp SceneGraph::AbstractObject::hasFeatures() @ce, @cpp firstFeature() @ce, @cpp lastFeature() @ce, @cpp SceneGraph::Object::hasChildren() @ce, @cpp firstChild() @ce and @cpp lastChild() @ce that were deprecated in 2015.05, use methods on linked list returned by @ref SceneGraph::AbstractObject::features() and @ref SceneGraph::Object::children() instead - Removed @cpp Platform::ScreenedApplication::frontScreen() @ce and @cpp Platform::ScreenedApplication::backScreen() @ce that were deprecated in 2015.05, use methods on linked list returned by @ref Platform::BasicScreenedApplication::screens() "Platform::ScreenedApplication::screens()" instead -

Removed @cpp *Framebuffer::bind(FramebufferTarget) @ce function that was deprecated in 2%15.05, use parameter-less @ref GL::Framebuffer::bind() "*Framebuffer::bind()" instead - Removed @cpp FramebufferTarget::ReadDraw @ce enum value that was deprecated in 2015.05, use separate @cpp FramebufferTarget::Read @ce and @cpp FramebufferTarget::Draw @ce values instead - Removed @ref GL::CubeMapTexture::imageSize() with explicit face parameter that was deprecated in 2015.05, use overload that returns one value for all faces instead - Removed the `Magnum/DebugMessage.h` header that was deprecated in 2015.05, use @ref Magnum/GL/DebugOutput.h instead - Removed the @cpp DebugMessage::Severity @ce enum that was deprecated in 2015.05, use @ref GL::DebugOutput::Severity instead - Removed @cpp DebugMessage::Callback @ce typedef, @cpp DebugMessage::setCallback() @ce and @cpp DebugMessage::setDefaultCallback() @ce function that were deprecated in 2015.05, use @ref GL::DebugOutput::Callback, @ref GL::DebugOutput::setCallback() and @ref GL::DebugOutput::setDefaultCallback() instead - Removed @cpp DebugMessage::maxLoggedMessages() @ce and @cpp DebugMessage::maxMessageLength() @ce functions that were deprecated in 2015.05, use @ref GL::DebugOutput::maxLoggedMessages() and @ref GL::DebugOutput::maxMessageLength() instead - Removed @cpp DebugMessage::setEnabled() @ce function and related values from @cpp DebugMessage::Source @ce enum that were deprecated in 2015.05, use @ref GL::DebugOutput::setEnabled() along with @ref GL::DebugOutput::Source, @ref GL::DebugOutput::Type and @ref GL::DebugOutput::Severity instead - Removed parameter-less @cpp *Query @ce constructor and parametrized @cpp *Query::begin() @ce function that were deprecated in 2015.05, use constructor with parameter and parameter-less @ref GL::SampleQuery::begin() "GL::*Query::begin()" instead - Removed `Timeline::setMinimalFrameTime()` that was deprecated since June 2015, use @ref Platform::Sdl2Application::setSwapInterval() "Platform::*Application::setSwapInterval()" and/or @ref Platform::Sdl2Application::setMinimalLoopPeriod() "Platform::*Application::setMinimalLoopPeriod()" instead - Removed `SceneGraph::Camera2D::setProjection()`, `SceneGraph::Camera3D::setOrthographic()` and `SceneGraph::Camera3D::setPerspective()` that were deprecated since June 2015, use @ref SceneGraph::Camera::setProjectionMatrix() in combination with @ref Matrix3::projection(), @ref Matrix4::orthographicProjection() and @ref Matrix4::perspectiveProjection() instead - Removed `SceneGraph::AbstractCamera`, `SceneGraph::AbstractBasicCamera2D`, `SceneGraph::AbstractBasicCamera3D`, `SceneGraph::AbstractCamera2D` and `SceneGraph::AbstractCamera3D` that were deprecated since June 2015, use @ref SceneGraph::Camera, @ref SceneGraph::BasicCamera2D, @ref SceneGraph::BasicCamera3D, @ref SceneGraph::Camera2D and @ref SceneGraph::Camera3D instead - Removed `Math::Matrix::IdentityType`, `Math::Matrix::ZeroType`, `Math::Matrix::Identity` and `Math::Matrix::Zero` that were deprecated since June 2015, use the @ref Math::IdentityInit and @ref Math::ZeroInit tags instead -
