Vladimír Vondruš	2cf9f28492	Shaders: resetting object ID FBs isn't needed for light tests.	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	35cb06fe1e	Shaders: use StringViews to make code generation a bit less shitty. Also it seems the reserve() call was wrong.	6 years ago
Vladimír Vondruš	903e2c213c	Shaders: properly use bitangents in Phong normal map calculation.	6 years ago
Vladimír Vondruš	2b36fd2136	MeshTools, Shaders: adapt thresholds for SwiftShader. The Phong bugfix causes some rounding errors to be larger than before.	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	63a78945e2	Shaders: there was a TODO so I implemented that TODO.	6 years ago
Vladimír Vondruš	4a632553a5	Shaders: doc++	6 years ago
Eric Undersander	8b8b9c456b	Shaders: remove incorrect light direction normalization in Phong.vert. Adapted slight changes in existing tests, the new ground truth now passes.	6 years ago
Vladimír Vondruš	0c48d1ccb8	Shaders: repro case for a bug in Phong light direction calculation. Interestingly enough / sadly none of the tests showed a clear difference when removing the incorrect normalization, so here's a dedicated test case. Sigh.	6 years ago
Vladimír Vondruš	9557de0534	Shaders,Trade: clarify use{less,ful}ness of specular alpha.	6 years ago
Vladimír Vondruš	c68ea7945b	Shaders: mention the setViewportSize() requirement clearer.	6 years ago
Vladimír Vondruš	cd48c59cab	Remove remaining APIs deprecated in 2018.10.	6 years ago
Vladimír Vondruš	5222cf3478	doc: change all "latest" additions/deprecations to 2020.06.	6 years ago
Vladimír Vondruš	c74e49b3f4	Shaders: make instancing finally work on ES2 / WebGL 1. This was stupid, eh? Blame Mesa and SwiftShader for not exposing ANGLE_instanced_arrays so the only way to test this for me was via the browser, which is practically impossible. Then found this by an accident. Pushing straight to master because YOLO.	6 years ago
Vladimír Vondruš	1436b7bc86	Shaders: fix various WebGL issues with new MeshVisualizer features. * Shader compilation failed with vertex, object and primitive ID enabled due to the NO_GEOMETRY_SHADER define not being correctly propagated * Enabling just vertex ID visualization on WebGL caused an assert in constructor, complaining that "at least one visualization feature has to be enabled", which is wrong * Defaults were not correctly set up for vertex ID rendering, causing all-black render when setColor() wasn't called * Forgot to list/bundle some ground truth test images for the test case, causing the test to fail due to files not found * The test asserted when generating mesh data due to an unhandled corner case * The test expected an ES2 assertion message on WebGL 2 * Flag::Wireframe now implicitly enables Flag::NoGeometryShader also on WebGL. This was done only for ES2 previously, but WebGL doesn't have (and won't have) geometry shaders, so it makes sense to do the same there.	6 years ago
Vladimír Vondruš	19e0e96d74	Updated copyright year.	6 years ago
Vladimír Vondruš	9d104a7e88	Shaders: document how to propagate generic attribs to shader code.	6 years ago
Vladimír Vondruš	28965d4887	Shaders: I happily forgot SwiftShader has broken gl_VertexID. Sigh.	6 years ago
Vladimír Vondruš	e8f36033f9	Shaders: GS is needed only for wireframe. So don't skip the test when rendering just object/primitive/.. ID. Turns out due to the skip this test was never executed on SwiftShader, and it thus needs some threshold bumping.	6 years ago
Vladimír Vondruš	698a7ed24c	Shaders: whoopsie.	6 years ago
Vladimír Vondruš	062055d20d	Shaders: add vertex ID visualization to MeshVisualizer. Helps visualizing face connectivity (or the lack of it).	6 years ago
Vladimír Vondruš	7a58bf5e42	Shaders: reorder code for consistency. It's InstancedObjectId and then PrimitiveId in the flags, so follow the same order in the code also.	6 years ago
Vladimír Vondruš	6eccc479f0	Shaders: simplify a bunch of repeated checks in shader code.	6 years ago
Vladimír Vondruš	b858385b84	Shaders: unify assert for common flags in 2D and 3D meshvisualizer.	6 years ago
Vladimír Vondruš	86a5a63af9	Test: most tests now pass on Zink as well. Just adding a bunch of extension checks that I thought I would never need again.	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	8b0ad005d8	Shaders: properly skip a test if image plugins are not available.	6 years ago
Vladimír Vondruš	97e3e2a8fe	MeshTools,Shaders: make the rendering tests pass on llvmpipe.	6 years ago
Michael Tao	e5a6f543a0	Shaders: ambient also changes color with VertexColor in Phong. Also adapt the test to explicitly check for this.	6 years ago
Vladimír Vondruš	65a2ced2a7	Make this compile and test cleanly with CORRADE_NO_ASSERT defined.	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	13c1fcdbfc	Shaders: forgot to list this file. Made the WebGL test fail.	6 years ago
Vladimír Vondruš	55685ea382	Shaders: implement instancing in Phong.	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	638f96f099	Shaders: be sure to list required extensions in generic attribs. Those aren't needed when the attributes are not used non-instanced, but that's extremely unlikely.	6 years ago
Vladimír Vondruš	c9ea6aba2e	Shaders: grumble.	6 years ago
Vladimír Vondruš	3e310cbd94	Shaders: note to self: save before commiting.	6 years ago

Vladimír Vondruš	46d492fcc9	Shaders: list forgotten MeshVisualizer test files.	6 years ago
Vladimír Vondruš	6b0d29bec2	Shaders: turn a construction test into an instanced one. Got more cases to test for.	6 years ago
Vladimír Vondruš	1cb7193034	Shaders: reorder MeshVisualizer docs.	6 years ago
Vladimír Vondruš	02525527a4	Shaders: ability to render instanced object ID in Flat/Phong.	6 years ago
Vladimír Vondruš	3759d26a7d	Shaders: NO, these are not layers.	6 years ago
Vladimír Vondruš	171e8a5301	Shaders: remove MeshVisualizer default behavior. It was rendering everything with a plain color, which is rather useless. Moreover it wasn't consistent with TBN visualization where you might actually want only the lines rendered and not the triangle.	6 years ago
Vladimír Vondruš	6299ece980	Shaders: test MeshVisualizer TBN direction defaults. Now possible, with compile() supporting the new attribs and primitives generating them. Finally out of this cyclic dependency hell, yay.	6 years ago
