Vladimír Vondruš	ac4971bd6f	Disable ARB_shading_language_420pack for Intel on Windows. The preprocessor string is exposed in GLSL even though the extension is not supported.	12 years ago
Vladimír Vondruš	5b3b722041	Detection of Intel Windows drivers.	12 years ago
Vladimír Vondruš	391ceae0c3	Minor cleanup.	12 years ago
Vladimír Vondruš	bfb58d0b55	ARB_direct_state_access support for creating queries. With DSA there is slightly different (but completely understandable) usage -- it's needed to specify the target upon creation, not deferring it to begin() call. Timestamp queries (TimeQuery::timestamp()) must now also be created with new TimeQuery::Target::Timestamp target. The old way (parameterless constructor and begin(Target)) is still supported, but is marked as deprecated and will be removed in future release. Also, using the old way the DSA function is simply not used. Also fixed SampleQuery test to account for cases where the driver might not support ARB_occlusion_query2.	12 years ago

Vladimír Vondruš	1c543cd26b	ARB_direct_state_access support for creating textures.	12 years ago
Vladimír Vondruš	b0741493f9	Preparation for ARB_direct_state_access GL 4.5 feature. Renamed all EXT_direct_state_access implementations to reflect the fact that these aren't using the ARB extension.	12 years ago
Vladimír Vondruš	a5c2efc8c0	Support glProgramUniform() calls from OpenGL ES 3.1. The code both supports new features and* is shorter, yay!	12 years ago
Vladimír Vondruš	dc312cda0d	Implemented indexed buffer binding. The indexed binding is allowed for only some types (atomic counters, uniforms, shader storage and transform feedback), thus we need separate enum for that. Because the bind() function will be used far more often than setTargetHint(), the original Target enum is now renamed to TargetHint and the new Target enum contains (in non-deprecated build) only three values. For backwards compatibility, though, we need to have all original Target values, thus the new Target enum contains also all other values from TargetHint, but they are marked as deprecated and (at least) run-time checked in bind() so they aren't accidentaly used for indexed binding. Similarly there are also deprecated Target overloads of Buffer() and setTargetHint(). It's ugly, but hopefully will suffice for now. This mess will be removed as soon as possible in some upcoming version.	12 years ago
Vladimír Vondruš	3e84a1848f	Added multi-unbind function to AbstractTexture. More efficient (no allocation) and also more convenient than calling e.g. unbind(7, {nullptr, nullptr, nullptr}).	12 years ago
Vladimír Vondruš	e193aa15c7	Added Mesh::maxElementIndex() limit query.	12 years ago
Vladimír Vondruš	5ad9ef56f4	Added Buffer::uniformOffsetAlignment() limit query.	12 years ago
Vladimír Vondruš	f246b41ad9	Replaced APPLE_vertex_array_object with ARB_vertex_array_object. We use the core functions without APPLE fallback.	12 years ago
Vladimír Vondruš	ea164f697d	Enabled new buffer functionality in ES 3.1.	12 years ago
Vladimír Vondruš	278877f8e3	Enabled 2D multisample textures in ES 3.1.	12 years ago
Vladimír Vondruš	ac0b63da0b	Enabled multisample texture limit queries in ES 3.1.	12 years ago
Vladimír Vondruš	10faa49363	Enabled texture image size queries in ES 3.1.	12 years ago
Vladimír Vondruš	4bc4a40c70	Enabled new shader functionality in ES 3.1.	12 years ago
Vladimír Vondruš	d3fd195849	Re-enable ES extensions everywhere except NaCl and Emscripten.	12 years ago
Vladimír Vondruš	a605306bb5	Added DebugMessage::setEnabled().	12 years ago
Vladimír Vondruš	4a6f53cdc8	Added non-allocating char array overload to DebugMessage::insert().	12 years ago
Vladimír Vondruš	24e88afefa	Decide between ANGLE/NV implementation for Framebuffer::blit() on ES. Currently both disabled until extension loader is in place.	12 years ago
Vladimír Vondruš	8c18bd0995	There is glDiscardSubFramebuffer() in EXT_discard_framebuffer. The relevant functions are now a no-op on ES2.	12 years ago
Vladimír Vondruš	eb32fb1c40	Proper no-op fallback for Framebuffer::invalidate(). The documentation of ARB_invalidate_subdata mentions that all the functions are really just a hint for the implementation to make some performance optimizations and they are not affecting behavior at all. So it's perfectly fine to do nothing if the extension is not supported. I didn't do this originally as I mistakenly thought that invalidating depth buffer would somehow behave the same as clearing it, but that's not the case.	12 years ago
Vladimír Vondruš	1b45a71ff5	Allocation-free overloads for *::setLabel(). In most cases the label is set directly from code, e.g.: texture.setLabel("diffuse-duck"); Avoiding conversion to std::string and passing char(&)[size] directly will avoid one allocation and deallocation. Better solution would be to use std::string_view everywhere, but we're not in C++17 yet.	12 years ago
Vladimír Vondruš	fcea05e316	Detecting whether ANGLE is used as GLES2 implementation.	12 years ago
Vladimír Vondruš	7f4a986c38	Added Context::detectedDriver(). A general way to detect drivers, which can be later used for applying driver-specific workarounds. Currently used for disabling ARB_explicit_uniform_location on AMD drivers.	12 years ago
Vladimír Vondruš	5998f46e12	Added support for glMultiDrawArrays()/glMultiDrawElements(). In OpenGL ES this is implemented in EXT_multi_draw_arrays extension, if it is not available, the functionality is emulated using sequence of normal draw() calls.	12 years ago
Vladimír Vondruš	4e50aeee31	Ability to reset internal state tracker.	12 years ago
Vladimír Vondruš	71a5766594	Added Mesh::addVertexBufferInstanced(). Functionality provided by GL 3.3 and ARB_instanced_arrays, on ES2 this is again implemented in three different extensions -- {ANGLE,EXT,NV}_instanced_arrays. They are disabled until Magnum has proper extension loading on ES.	12 years ago
Vladimír Vondruš	20df20de0f	Support for instanced mesh drawing and base instance. On desktop GL this is provided by ARB_draw_instanced (GL 3.1). Base instance is available only on desktop GL (4.2, ARB_base_instance). In ES2 the instanced functionality is provided by three (!) different extensions (ANGLE_instanced_arrays, EXT_draw_instanced, NV_draw_instanced), the proper implementation is chosen on context creation based on what extension is available. Though we don't have extension loader for ES yet, thus all these extensions are disabled and the implementation has assertion in it. Added blind test which tests only that something has been drawn and no errors were emitted, but not whether the right command is used. I'll probably need to check this later, because the Mesh::draw() behemoth is going slightly out of hand :)	12 years ago
Vladimír Vondruš	2ae7bfaf14	Max texture LOD bias _is_ available in OpenGL ES 3.	12 years ago
Vladimír Vondruš	d772f51050	Hide texture state members which are not used on ES. Shaved eight bytes off total memory footprint, yay!	12 years ago
Vladimír Vondruš	54cb177bb0	Properly initialize variables for texture limits in state tracker. And I was wondering how it is possible that there new NVidia drivers were allowing up to 32 PB textures on my humble laptop graphics :)	12 years ago
Vladimír Vondruš	74ae14b44a	Remove unused members from ES build.	12 years ago
Vladimír Vondruš	8c0c80a5c3	Implemented ARB_texture_swizzle.	12 years ago
Vladimír Vondruš	1b1ad41ae1	Renamed internal function to avoid name clashes.	12 years ago
Vladimír Vondruš	2cbcdeaeb4	Queries for max supported texture size.	12 years ago
Vladimír Vondruš	4f4131b320	Implemented texture LOD parameters.	12 years ago
Vladimír Vondruš	0a2b8088a6	Added MultisampleTexture::setStorage(). With this function multisample texture implementation is pretty much done. Also implemented all the tests.	12 years ago
Vladimír Vondruš	6f0a238376	Disable also NV_framebuffer_blit on ES2. Until we have proper extension loader implemented (caused FramebufferGLTest to assert). On a related note, NVidia drivers 334.21 support a lot of ES2 extensions. Wow.	12 years ago
Vladimír Vondruš	cc66fa76ba	Support ARB_multi_bind for textures.	12 years ago
Vladimír Vondruš	580a723d61	Added *Texture::unbind(). Will be used in fallback implementation of multi-bind.	12 years ago
Vladimír Vondruš	e2abc39766	Save texture target along with ID in state tracker. Makes later unbinding easier (i.e. we don't need to cycle through all possible/supported targets and call glBindTexture(target, 0) with each.	12 years ago
Vladimír Vondruš	bf1d2e26fa	Support for setting border color on integer textures. EXT_texture_integer implementation is now complete. Just GL 3.0 subset, though, as apparently glClearColorI*() is not part of it.	12 years ago
Vladimír Vondruš	0955390ca8	Follow OpenGL terminology for texture binding units. Until now the textures were bound to layers, which was rather confusing, especially when binding layered textures to layers (gaah). Also the wording might have implied that each texture must be in some layer in order to make it usable in shader. This is no longer the case with (yet unimplemented) bindless texture, so another reason to remove the confusion. All occurences of texture layers were replaced texture binding units to follow OpenGL naming. It was mostly in the docs, except for already-deprecated *Layer enums in shaders, but they will be removed soon anyway.	12 years ago
Vladimír Vondruš	7a1789470a	Initial ARB_multi_bind usage in *Texture::bind().	12 years ago
