With pixel pack/unpack support it will be possible to create views onto
sub-images, renamed the class to reflect that.
The old Magnum/ImageReference.h and ImageReference types are now aliases
to ImageView.h and ImageView types, are marked as deprecated and will be
removed in future release.
Similarly to what's now done with NoInit tags for Containers::Array and
all math types such as Vector, there's now NoCreate tag for creating
wrappers without actually creating the underlying OpenGL object. The
instance is then equivalent to moved-from state. Useful to avoid
needless creation/deletion of OpenGL object in case you would overwrite
the instance later anyway:
Mesh mesh{NoCreate};
std::unique_ptr<Buffer> indices, vertices;
std::tie(mesh, indices, vertices) = MeshTools:compile(...);
I wanted to preserve the parameter-less constructor of tests, but WINAPI
requires fairly ugly entagled set of functions, passing HWND around,
which required storing it in a global var and hoping it is properly
initialized when querying it for it to be passed to application
constructor.
When this was done, it was now fairly easy to support passing also
argv/argc to application constructor, which in the future will enable
selective disabling of extensions for even better test coverage.
This however needed slightly different main() function and thus we now
have MAGNUM_GL_TEST_MAIN() instead of CORRADE_TEST_MAIN(). Using the
latter will result in an assert inside std::optional.
Similar to Framebuffer::read(), it's now possible to get texture image
also in single statement:
Image2D image = texture.image(0, {ColorFormat::RGBA, ColorType::UnsignedByte});
in comparison to the previous way:
Image2D image{ColorFormat::RGBA, ColorType::UnsignedByte};
texture.image(0, image);
The previous way is still kept in the API and not deprecated, as it
might be more usable in some cases.
As glGen*() only reserves object name without creating it, it must be
ensured that the object is created before calling functions which expect
already created object (such as glObjectLabel() or glBindTextures()).
Allows me to remove quite a lot hacks in the tests.
With ARB_multi_bind it is needed to associate the texture with some
target before calling glBindTextures(), otherwise the texture is
treated as invalid.
Each texture has slightly different usage requirements and having
everything under one generic class is not worth the additional runtime
checks and whatnot. The current way with Texture::Target enum
(hopefully not too widely used) is now deprecated and will be removed in
some future release. However general Texture1D/2D/3D usage is not
changed in any way.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Finally a non-confusing name, hopefully. Sorry it took me too long. The
original Sampler::maxAnisotropy() (and also
Sampler::maxSupportedAnisotropy()) is now alias to the new one, is
marked as deprecated and will be removed in future release.
