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. Co-authored-by: Squareys <squareys@googlemail.com>	3 years ago
Vladimír Vondruš	8c62f8d736	Shaders: doc++ A considerable chunk of the docs mentioned that there has to be one ProjectionUniform3D per draw. Probably a copypaste error from the case where there's a combined TrannsformationProjectionUniform3D, which is one per draw. Sorry for the confusion. There was also quite a lot of documentation content referencing the old deprecated constructors. Fixed now.	3 years ago
Vladimír Vondruš	40593113f6	Shaders: drop nasty workarounds for Clang 3.8. The minimum Clang version got bumped to 6 almost half a year ago in `5e3b610613` so these are not needed anymore. More burning code!	4 years ago
Vladimír Vondruš	822fa0d644	Updated copyright year.	4 years ago
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	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	0512edf754	Shaders: Clang 3.8, WHY are you runing my nice tidy paddings.	5 years ago
Vladimír Vondruš	ef9da0ec96	Shaders: add UBO support to all shaders.	5 years ago
Vladimír Vondruš	2066d82ea4	Shaders: suffix all existing shaders with GL. To make room for Vulkan shaders. Also renaming the headers, of course everything is still aliased to the old names (and marked as deprecated).	5 years ago
Vladimír Vondruš	3d136503d8	Updated copyright year.	5 years ago
Vladimír Vondruš	40ee8f0934	Shaders: document relation to glAlphaFunc().	5 years ago
Vladimír Vondruš	7257bbb871	Shaders: rework Phong to support directional and attenuated point lights. This is a -- long overdue -- breaking change to the rendering output of this shader, finally adding support for lights that get darker over distance. The attenuation equation is basically what's documented in LightData, and the distinction between directional and point lights is made using a newly added the fourth component of position (which means the old three-component setters are all deprecated). This allows the shader code to be practically branchless, which I find to be nice. This breaks basically all rendering output so all existing Phong and MeshTools::compile() test outputs had to be regenerated.	6 years ago
Vladimír Vondruš	5222cf3478	doc: change all "latest" additions/deprecations to 2020.06.	6 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	c03ed3af75	doc: show how to set up blending for alpha / transparency. Hopefully more discoverable now also.	6 years ago
Vladimír Vondruš	a1f1f66c04	Shaders: implement instancing in Flat.	6 years ago
Vladimír Vondruš	e6010388c3	Shaders: reorganize the Flat and Phong docs. Dry blabber followed by dry code is worse than those two interleaved.	6 years ago
Vladimír Vondruš	02525527a4	Shaders: ability to render instanced object ID in Flat/Phong.	6 years ago
Vladimír Vondruš	0c7e3bf96a	Shaders: minor cleanup.	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	32d49db402	GL: mesh.draw(shader) -> shader.draw(mesh). As usual, the old APIs are still present, but marked as deprecated. Existing code is not updated yet to ensure I didn't break anything with this. This way it's much more intuitive and makes the code shorter and nicer in many cases. Shaders are now also able to hide irrelevant draw/dispatch APIs to avoid accidents.	6 years ago
Vladimír Vondruš	a920722839	doc: label deprecated APIs and stuff new since 2019.10 with version info. Should make new things more discoverable, avoid confusion when a documented API isn't there and reduce the need for maintaining multiple separate versions of the docs.	7 years ago
Vladimír Vondruš	b4f88f00ab	Remove last remaining APIs deprecated in 2018.04.	7 years ago
Vladimír Vondruš	d06914a1bd	doc: hint that Optional is a safer NoCreate.	7 years ago
Vladimír Vondruš	a0f0015211	Shaders: de-inline uniform setters. Reduces includes in the header quite a lot, yay.	7 years ago
Vladimír Vondruš	5617cb5199	Shaders: vertex color support in Phong and Flat.	7 years ago
Vladimír Vondruš	a3c8d8ec63	Shaders: allow Phong with zero lights. Which makes it equivalent to Flat3D. Useful to reduce complexity in apps that render models with pre-baked lighting.	7 years ago
Vladimír Vondruš	c78d6d9adc	Shaders: doc++	7 years ago

Vladimír Vondruš	02f0e0aeb9	Doc++	8 years ago
Vladimír Vondruš	0e9cb6945e	Shaders: define reasonable uniform defaults for all shaders. Plus a bit of cleanup / fixing broken English.	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	5201176cdb	Shaders: assert texturing is enabled when calling Flat::bindTexture().	8 years ago
Vladimír Vondruš	c26075427b	Doxygen. Doxygen IS BROKEN BEYOND REPAIR. I introduced strong enum with values, in a subnamespace, that have the same name as completely unrelated typedefs. Guess what?! It breaks ALL LINKS TO THOSE TYPEDEFS! EVERYWHERE!!!	8 years ago
Vladimír Vondruš	f7122d3ce6	Shaders: explicitly list deleted/defaulted copy/move constructor. Two reasons: * documentation * making it actually work because the rules are so complex and ever changing that a thing I thought "just worked" in fact did not work at all The Vector tests now compile again.	8 years ago
Vladimír Vondruš	adb4547ba0	Split the OpenGL layer out, pt 20: adapted Shaders.	8 years ago
Vladimír Vondruš	7917741346	Shaders: rename texture binding functions from set() to bind(). This better reflects that the functions modify a global state instead of a shader-local state and so rebinding may be necessary (unlike with uniforms, which get preserved). The old set() functions are now inline aliases to the bind() functions, are marked as deprecated and will be removed in some future release.	8 years ago
Vladimír Vondruš	bc8b8f159a	doc: there's no latex output anyway.	8 years ago
Vladimír Vondruš	3906f533bb	doc: compiled code snippets for the Shaders namespace. Also not really without errors.	8 years ago
Vladimír Vondruš	6dffc0a91e	Shaders: documentation update for the new theme. Also made the shader image background transparent to better fit in the docs and updated the images to match site colors.	8 years ago
Vladimír Vondruš	623fa97970	Updated copyright year.	8 years ago
Vladimír Vondruš	7a16273e5d	Updated copyright year.	9 years ago
Vladimír Vondruš	d6f5f43d60	Shaders: modernize coding style. * Always prefix private members with an underscore * Use in-class initialization of the uniform locations * Use {} for default flag value	9 years ago
Vladimír Vondruš	1e8a5c927b	Shaders: added NoCreate constructors to all classes. Makes it possible to have instance of them even before any context is active.	9 years ago
