Vladimír Vondruš	420b3435f2	Use glGetStringi() on Emscripten/WebGL 2. Available in recent versions.	11 years ago
Vladimír Vondruš	1d2485fd28	Pixel storage support, part 7: state tracking for glPixelStore().	11 years ago
Vladimír Vondruš	6110ba0922	Pixel storage support, part 3: EXT_unpack_subimage and NV_pack_subimage. ES 2.0 extensions to match ES3/desktop functionality. The enums from NV_pack_subimage are not available in gl.xml from Khronos, I would need to use hardcoded value.	11 years ago
Vladimír Vondruš	7aef7f44f5	Compressed image support, part 5: added EXT_texture_compression_s3tc. And related WebGL extension. Why the hell do they need their own naming again?!	11 years ago
Vladimír Vondruš	cb44f06359	Added NV_shader_noperspective_interpolation ES3 extension.	11 years ago
Vladimír Vondruš	361ab62fe9	Added ANDROID_extension_pack_es31a extensions. Just added them to the list, nothing integrated or implemented yet. Also added some more stuff into OpenGL mapping table, as I apparently forgot some entries.	11 years ago
Vladimír Vondruš	0dba2601e3	Added KHR_blend_equation_advanced{,_coherent} extensions.	11 years ago
Vladimír Vondruš	87e964ce69	Fixed build on GCC < 5.1 and Clang. Apparently I can't do a change without breaking stuff somewhere. Sigh.	11 years ago
Vladimír Vondruš	387f3b78d6	Ability to move-construct Context. Useful in this case: std::optional<Platform::Context> context; context = Platform::Context{}; This was currently possible only with calling context.emplace(), which in my opinion is confusing and looks like a no-op. Move assignment is still not allowed, because having two separate state trackers (and deleting one of them) currently makes no sense.	11 years ago
Vladimír Vondruš	a8f04ec7a9	Proper naming of private variable.	11 years ago
Vladimír Vondruš	4720a8db96	Implement NV_polygon_mode ES extension.	11 years ago
Vladimír Vondruš	df6acb10ab	Implement EXT_sRGB_write_control ES extension.	11 years ago
Vladimír Vondruš	6313791812	Don't expose EXT_sRGB on ES3/WebGL2 builds. It is superseded by core functionality. The only annoyance is that you need to use TextureFormat::SRGB in ES2 and TextureFormat::SRGB8 in ES3, but that's with many other formats anyway. Also apparently the unsized format is still allowed in core desktop GL, which is a shame.	11 years ago
Vladimír Vondruš	8648d93324	Support Internet Explorer. It claims to have WebGL 0.94.	11 years ago
Vladimír Vondruš	8321a7ce08	Document the non-obvious behavior.	11 years ago
Vladimír Vondruš	d34cbb73b7	Clarified and cleaned up WebGL extension support list. For more clarity it's now better to explicitly list all extensions for each API even though they might get duplicated. For WebGL they also link to WebGL spec, which might contain a bit more info.	11 years ago
Vladimír Vondruš	96d99ac4f8	Remove unused Context::{major,minor}Version() functions. Superseeded by Context::version() and various utilities around Version enum.	11 years ago
Vladimír Vondruš	aa31c0e0f5	Use glGetString(GL_EXTENSIONS) instead of glGetStringi() on WebGL 2. Or at least until Emscripten has implementation for it.	11 years ago
Vladimír Vondruš	cb6299458c	Don't query GL_{MMAJOR,MINOR}_VERSION on WebGL 2. It doesn't make any sense -- WebGL 2 doesn't provide any equivalent functionality for this and so I don't even know what values should this return (3.0? 2.0?). Instead I just check for "WebGL 2" string prefix and treat it as ES 3.0.	11 years ago
Vladimír Vondruš	d3e83f797d	Expose CHROMIUM_map_sub only for NaCl. It's not even in official registry.	11 years ago
Vladimír Vondruš	92e923d056	First-class WebGL support, part 14: reduced available extensions. This was the actual problem. Most of ES extensions are not available in WebGL, thus the GL headers and the code was far more bloated than it needed to be. The GL header is now reduced and the previous 13 commits were disabling features that aren't actually available in WebGL. The final executable size is reduced by ~50 kB, which actually isn't much, but still something. Some ES extensions (ANGLE_depth_texture and ANGLE_instanced_arrays) have now WEBGL_* prefix. I'm still using the original prefix in the implementation because there are headers for these, but in public docs and elsewhere they are exposed with WEBGL_*.	11 years ago
Vladimír Vondruš	61d9697f00	First-class WebGL support, part 13: reduce version enum.	11 years ago
Vladimír Vondruš	9f96ed4658	First-class WebGL support, part 11: no context flags.	11 years ago
Vladimír Vondruš	295b909c1c	Print error if transform feedback header is used in OpenGL ES 2.0 build.	11 years ago
Vladimír Vondruš	eaf849f659	Undef privately used macro in all cases.	11 years ago
Vladimír Vondruš	db1142837c	Clarified and updated *Framebuffer::mapForDraw() implementations. In OpenGL ES 2.0 there is EXT_draw_buffers, which I overlooked somehow, so I added it to extension list and included in the implementation. It combines NV_draw_buffers and NV_fbo_color_attachments, so the implementation now selects one of the two based on which extension is supported, preferring the EXT one. Updated the documentation to be less confusing, fixed extension links. Also the single-output mapForDraw() is not handled separately on ES anymore and just calls DrawBuffers implementation with single parameter, resulting in less generated code. EXT_draw_buffers can also be called on default framebuffer and apparently in ES there is no way to map front framebuffer for drawing, so I removed it from the DefaultFramebuffer::DrawAttachment enum.	11 years ago
Vladimír Vondruš	ec528aca6f	There are no new extensions in ES 3.1.	11 years ago
Vladimír Vondruš	70150a8845	Don't use `return std::move()` where it is not needed.	11 years ago
Vladimír Vondruš	6488fe6e75	Oh, it's 2015 already.	11 years ago
Vladimír Vondruš	9d6c52cd92	Alphabetically reorder extension groups.	12 years ago
Vladimír Vondruš	6f355c564d	Initial transform feedback implementation. Full support for EXT_transform_feedback, transform feedback objects from ARB_transform_feedback2 and equivalent OpenGL ES 3.0 functionality. Example usage is in src/Magnum/Test/TransformFeedbackGLTest.cpp, I'll add some example later.	12 years ago
Vladimír Vondruš	4cd4cbf148	Added OES_texture_npot ES extension to the list. Nothing new added, but the user can rely on presence of this extension as it removes some restrictions from the speccs.	12 years ago
Vladimír Vondruš	1659f68d59	Print some more info when initializing Context. Then also don't display this information duplicated in magnum-info.	12 years ago
Vladimír Vondruš	e739c86e72	Replaced EXT_framebuffer_sRGB with ARB_framebuffer_sRGB. Also seems to have wider support than the EXT version.	12 years ago
Vladimír Vondruš	4c86d04042	Support for ARB_robustness_isolation. Easier than forgetting about what I read and then learning that all again later.	12 years ago
Vladimír Vondruš	1d8b0ba268	Added remaining non-core ARB/KHR extensions to the list.	12 years ago
Vladimír Vondruš	64e85966de	Replaced NV_half_float with hopefully more standard ARB_half_float. According to reports on delphigl.de this extension is far more supported in comparison to the NV version (and also there's much less FF cruft in the specification).	12 years ago
Vladimír Vondruš	b251b1b0c5	Mark also all GL 4.5 extensions as supported if GL 4.5 is supported. Oh god, it got to the point where I should write an HOWTO for myself.	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	0c37555079	Removed APPLE_flush_buffer_range from extension list. Not mentioned anywhere, doesn't add anything to ARB_map_buffer_range.	12 years ago
Vladimír Vondruš	7b5d9a63f1	Initial support for OpenGL 4.5.	12 years ago
Vladimír Vondruš	8e79d1877e	Initial support for OpenGL ES 3.1.	12 years ago
Vladimír Vondruš	6c766df568	Move function pointer loading into platform-specific class. This way it will be possible decouple the main library from platform-specific GLX/WGL/CGL/EGL... API.	12 years ago
Vladimír Vondruš	dfec071575	Less strict version string comparison in Context. Not all drivers return "2.1 Vendor", there is also "2.1.2 NVIDIA" (and probably more).	12 years ago
Vladimír Vondruš	a9a5ead13d	Dropped GCC 4.6 support.	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	4b6ae7afe6	Support for EXT_texture_sRGB_decode.	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
