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	c2a18f290d	Shaders: pack Phong light offset and count into 16 bits each. To make room for two more 16-bit skinning-related values in the PhongDrawUniform -- joint offset for multidraw and per-instance joint count for instancing. Originally I made those full 32 bits because I wanted to provide an option to have a 64-bit light mask there instead of an offset + count. But the mask is not really driver-friendly as going over the bits and skipping zeros was behaving like if each pixel was affected by 64 lights -- an absolute perf nightmare. I might reconsider this again later, but for now that doesn't seem to make sense, and I need to put the skinning-related info somewhere without inflating the per-draw uniform by another 16-byte vector.	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	229641d2ac	Shaders: support object ID textures in the PhongGL shader.	4 years ago
Vladimír Vondruš	cc74784d40	Shaders: ability to disable Phong specular contribution. In cases when specular highlights are not desired, results in 30% speedup (on Intel) and ~25% speedup on AMD, compared to setting the specular color to transparent black. Testing was easy thanks to already having a ground truth image for this case.	5 years ago
Vladimír Vondruš	afd8d7c8f9	Shaders: introduce Phong::Flag::LightCulling. After several failed attempts to make UBO performance not suck on Intel Mesa and Windows drivers, I ended up hiding the dynamic aspect under a flag. That way it's still possible to get the proper perf in UBO workflows that don't do light culling, and for workflows where light culling matters the 2x slowdown might be still better than looping through several extra lights that don't contribute anything.	5 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	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	beecb8fb82	Shaders: fix copypaste errors in Phong setter docs.	5 years ago
Vladimír Vondruš	3d136503d8	Updated copyright year.	5 years ago
Vladimír Vondruš	d00d1cb781	Shaders: initialize all members also with NoCreate. Otherwise the _lightCount gets a random value, which makes debugging of accidentally not created instances harder than strictly necessary.	5 years ago
Vladimír Vondruš	40ee8f0934	Shaders: document relation to glAlphaFunc().	5 years ago
Vladimír Vondruš	567b15486f	Shaders: add an ability to control specular light color to Phong.	6 years ago
Vladimír Vondruš	f69644936e	Shaders: reference the normal mapping docs from relevant APIs.	6 years ago
Vladimír Vondruš	25463db8a6	Shaders: alpha doesn't make sense for light colors. I basically deprecated half of the Phong shader API. Sigh. Enjoy updating your code.	6 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	903e2c213c	Shaders: properly use bitangents in Phong normal map calculation.	6 years ago
Vladimír Vondruš	5285dcc986	Shaders: add a normal texture scale parameter to Phong. It's needed to support the new material attributes supported by glTF. The test output is slightly different as the normal coming from the texture wasn't normalized before.	6 years ago
Vladimír Vondruš	9557de0534	Shaders,Trade: clarify use{less,ful}ness of specular alpha.	6 years ago
Vladimír Vondruš	5222cf3478	doc: change all "latest" additions/deprecations to 2020.06.	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	55685ea382	Shaders: implement instancing in Phong.	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	c82a34c157	Shaders: doc++	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	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	d5e4de772e	Shaders: doc++	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	87ac8a8cd2	Shaders: support object ID output in Flat and Phong.	7 years ago
Vladimír Vondruš	0cb4ded506	Shaders: add normal texture support to Phong. Note -- since there are no visual tests for Phong yet, this is done in the least intrusive manner to avoid breaking current functionality. It's likely very underperforming due to the matric calculation per fragment, it'll get optimized once I have proper tests.	7 years ago

Vladimír Vondruš	fd1572a3a3	Shaders: default ambient color in Phong to transparent black. Makes it possible to support alpha-masked drawing out of the box, shouldn't have any negative effect on anything else.	8 years ago
