Vladimír Vondruš	ee2d56c3d3	Shaders: clean up redundant preprocessor elif condition in a shader.	3 years ago
Vladimír Vondruš	b38d3eea89	Shaders: add SSBO support to all shaders. For when there's so much to render that it wouldn't fit into an UBO and splitting draw calls and binding buffers under an offset is unwanted overhead.	3 years ago
Vladimír Vondruš	506841f4a9	Shaders: initial implementation of a line shader. The shader requires the input data to be laid out in a rather specific way, and there will be a dedicated MeshTools utility for it in the following commits. For independence though, the shader tests use a custom helper. The initial implementation has certain corner cases which will be eventually resolved. For now they are pinned down with repro cases in the test. But apart from that, it's pretty much usable in practice. Remaining join styles (round and miter-clip) as well as stipple support will eventually follow as well.	3 years ago
Vladimír Vondruš	b3e6bee913	Shaders: minor cleanup.	3 years ago
Vladimír Vondruš	89a6eb22de	Shaders: skinning support in FlatGL, MeshVisualizerGL and PhongGL. High-level docs with examples will be written once there's corresponding support in MeshTools::compile() and in importer plugins, as skinned meshes are usually brought in from files, never set up directly.

Vladimír Vondruš	b2a400f898	Shaders: support object ID textures in the FlatGL shader.	4 years ago
Vladimír Vondruš	78d9694676	Shaders: assume materialId is 0 if MATERIAL_COUNT is 1. Unlike the drawId optimization before, there's no possibility to check this anywhere, so the assumption is just documented. On an Intel 630 this resulted in further significant reduction for the single-draw single-material case, down to 260 from 440 in the previous commit, about a 45% reduction compared to the original 550 ms; multidraw case is still around the 550 there.	5 years ago
Vladimír Vondruš	c92d608aa7	Shaders: assume drawOffset is 0 if DRAW_COUNT is 1. This is always true in the single-draw case, since setDrawOffset() asserts on this. In the multi-draw case this optimization doesn't make sense, because it doesn't make sense to create a multidraw shader with just one draw. On an Intel 630 GPU this resulted in single-draw single-material Phong to go from 550 ms to 440, which is roughly a 20% improvement. For the simpler shaders the difference is even higher. The multidraw numbers stayed the same as before, obviously.	5 years ago
Vladimír Vondruš	95379ace8e	Shaders: support array textures in Flat and Phong.	5 years ago
Vladimír Vondruš	a2f8a920da	Shaders: supply Flat material information in a separate UBO as well. While it's one additional indirection (that has an extra cost on Intel GPUs apparently, like with Phong and MeshVisualizer and DistanceFieldVector already), with the assumption that draws usually share the material info it allows to cram more draws into the 16/64k UBO limit as the per-draw data are now one vec4 smaller. For the indirection overhead I can imagine adding a new flag which makes material mapping implicit (materialId == drawId). That seems to put the benchmark numbers back to the original speed. Same could be done for other shaders.	5 years ago
Vladimír Vondruš	2c09a2a1e6	Shaders: multidraw support in all builtin shaders.	5 years ago
Vladimír Vondruš	ef9da0ec96	Shaders: add UBO support to all shaders.	5 years ago
Vladimír Vondruš	d3e11765ac	Shaders: EXPLICIT_TEXTURE_LAYER is very misleading. I went through renaming this on many places quite some time ago, but this one slipped through. Now that UBOs will be a thing, rename to EXPLICIT_BINDING instead of EXPLICIT_UNIFORM_BINDING.	5 years ago
Vladimír Vondruš	9f0a61e76e	Shaders: group things together also in GLSL sources. It was also becoming quite a mess in there.	5 years ago
Vladimír Vondruš	3d136503d8	Updated copyright year.	5 years ago
Vladimír Vondruš	19e0e96d74	Updated copyright year.	6 years ago
Vladimír Vondruš	881a50f7fa	Shaders: clarify that object ID features need GL 3.0 extensions. Important for Zink, which has neither of them.	6 years ago
Vladimír Vondruš	02525527a4	Shaders: ability to render instanced object ID in Flat/Phong.	6 years ago
Vladimír Vondruš	9a06b3515b	Shaders: implement texture coordinate transformation for all shaders. Except MeshVisualizer and VertexColor, which don't have any texturing, so there it's not needed. In most cases the tests are reusing existing ground truth files and only modifying transformations / flipping images.	6 years ago
Vladimír Vondruš	5617cb5199	Shaders: vertex color support in Phong and Flat.	7 years ago
Vladimír Vondruš	87ac8a8cd2	Shaders: support object ID output in Flat and Phong.	7 years ago
Vladimír Vondruš	08f6615048	Shaders: make alpha mask = 1.0 do what's expected. Yay tests!	7 years ago
Vladimír Vondruš	e6b7aa12fa	Updated copyright year.	7 years ago
Vladimír Vondruš	b5dc42f332	Shaders: I f'ed up the Flat shader defaults, again. Leftover from `0e9cb6945e`. Documented properly, but not implemented. I need the shader tests ASAP.	8 years ago
Vladimír Vondruš	daf287d2a6	Shaders: classical alpha masking support in Phong and Flat. Slow and ugly, is here only for making quick'n'dirty alpha masked drawing without a need for blending or depth sorting. Oh and also to support the glTF alpha mask feature. Again, beware: slow.	8 years ago

Vladimír Vondruš	23646e6690	Hell, this project is big.	10 years ago
Vladimír Vondruš	f52a086f8e	Shaders: clean up Flat, set default color only for textured one. Also probably fixed a few issues when compiling the shader on older GLSL and GLSL ES (floating point literal suffixed, missing precision qualifiers). And less crazy preprocessor.	11 years ago
Vladimír Vondruš	6488fe6e75	Oh, it's 2015 already.	11 years ago
Vladimír Vondruš	6f0ba96cb6	Happy new year too.	12 years ago
Vladimír Vondruš	45a10cefdf	Making includes absolute, part 1: moving files around. 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.	13 years ago
Vladimír Vondruš	dfeeff779b	Shaders: oops.	13 years ago
Miguel Martin	0670f59c95	Added colour uniform to flat shader (event when texturing is enabled) This enables blending and transparency Default colour is white (and fully opaque)	13 years ago
Vladimír Vondruš	ef83211c46	Shaders: fix textured Flat on systems w/o ARB_explicit_attribute_location. How could I possibly overlook this.	13 years ago
Vladimír Vondruš	c9e8d270a5	Shaders: okay, I admit, my NVidia really _is_ forgiving in GLSL ES. The tests didn't catch this at all.	13 years ago
Vladimír Vondruš	60d8d1af16	Shaders: textured version of Flat shader.	13 years ago
Vladimír Vondruš	623fda0dc7	Shaders: removed superfluous `*Shader` suffix from class names.	13 years ago

Vladimír Vondruš	c5ab86794b	Relicensing to MIT/Expat license, part 3: source files. Added license header also to shader sources. Hopefully it won't harm compilation times too much.	13 years ago
Vladimír Vondruš	dc798b7320	Shaders: added missing 3D version of FlatShader vertex shader. Fragment shader is common for both 2D and 3D.	13 years ago
Vladimír Vondruš	7a894e97a0	Using ARB_explicit_uniform_location in shaders. The backwards compatibility fully kills the purpose, but at least I can test the feature somewhere :-)	14 years ago

Vladimír Vondruš	81b69f17e1	Shaders: another iteration in porting of Phong and Flat shaders to GLES. Hope the reduced precision won't hurt.	14 years ago
Vladimír Vondruš	6f6d3d09b2	Blind port of FlatShader to OpenGL 2.1 and OpenGL ES 2.0.	14 years ago
Vladimír Vondruš	d46bc34390	Moved flat shader from internal physics implementation to Shaders. It is so general that it can be reused elsewhere.	14 years ago
