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	b3da48a0ae	Shaders: properly test Phong one-by-one light property setters. Testing that they don't assert isn't enough.	6 years ago
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	759038c83c	Trade: proper spacing around binary math operators in LightData docs.	6 years ago
Vladimír Vondruš	8b665884f0	Trade: change LightData range attenuation to do 1 + d^2 in denominator. Otherwise the attenuation would explode to infinity at distance < 1, which doesn't make any sense. This, together with the square of the nominator, is different from the recommended glTF attenuation in KHR_lights_punctial, but because I couldn't find any relevant discussion on the equation used there, I'll assume it's just wrong. Sigh.	6 years ago
Vladimír Vondruš	88879298a7	sceneconverter: enumerate lights in --info.	6 years ago
Vladimír Vondruš	d1949a4941	Trade: add ambient light type as well. At first I thought it could be done with a point light and a (1, 0, 0) attenuation, but that still has a direction, so no.	6 years ago
Vladimír Vondruš	2b987499e2	Trade: add attenuation, range and cone angle parameters to LightData. And document how all those go together.	6 years ago
Vladimír Vondruš	18a05309e9	Platform: added view-taking Platform::GlfwApplication::setWindowIcon(). For some reason there's just an initializer-list overload, which is rather useless.	6 years ago
Vladimír Vondruš	6be0248e9c	imageconverter,sceneconverter: add -I and -C short variants. I'm tired of typing all that.	6 years ago
Vladimír Vondruš	ec7592d413	imageconverter: add an --in-place option. I'm using it to compress ground truth TGA images for shader tests because TgaImageConverter doesn't implement RLE yet.	6 years ago
Vladimír Vondruš	884b315ca5	AnySceneImporter: support skin import.	6 years ago
Vladimír Vondruš	051b715c12	Platform: reference useful APIs and docs from setWindowIcon().	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	8449fecc1c	Trade: expand a TODO.	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	ec22b33e01	Trade: document how normal texture scale is meant to be applied.	6 years ago
Vladimír Vondruš	8bbbd4a994	GL: document uselessness of certain polygon offsets for future me. I bet this is at least the fifth time I ran into this. And always immediately forgot after.	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	9c14f1d367	Trade: clarify AbstractImporter::do*Count() error handling.	6 years ago
Vladimír Vondruš	ddb7185417	Trade: make AbstractImporter::defaultScene() const. Makes more sense as the function isn't expected to fail (and thus any kind of lazy population is not possible as it would be too late for error checks anyway). Not updating interface strings even though this is an ABI break because we're doing that right after the skin import interface bump.	6 years ago
Vladimír Vondruš	5217f48499	Trade: disallow custom deleters in AbstractImporter::skinXD().	6 years ago
Vladimír Vondruš	8c24ea19d3	Trade: skin import in AbstractImporter.	6 years ago

Vladimír Vondruš	b9413d3ff5	doc: avoid plugin interface strings getting out of sync with docs.	6 years ago
Vladimír Vondruš	fc7ebcd409	Appropriately reference MeshTools::primitiveCount(). Not from GL::Mesh, because it doesn't accept GL-specific enums.	6 years ago
Vladimír Vondruš	5e5fd681f8	MeshTools: doc++	6 years ago
Vladimír Vondruš	b77eafb9de	MeshTools: add generateQuadIndices().	6 years ago
Vladimír Vondruš	d01364ca1f	Math: document more what's cross() good for.	6 years ago
Vladimír Vondruš	3bfe0f1d7f	Trade: minor test cleanup.	6 years ago
Vladimír Vondruš	1be899d7fb	Trade: doc++	6 years ago
janos	12529efa89	Trade: various doc fixes.	6 years ago
Vladimír Vondruš	8c5a2d6a88	Platform: Xlib strikes again, this time with #define Bool int. THe new MaterialData APIs introduce MaterialAttributeType::Bool and everything kinda explodes with that. Seriously, what were the people in 1979 thinking.	6 years ago
Vladimír Vondruš	3ffcdf1865	Trade: improve compat of deprecated PhongMaterialData::textureMatrix(). The new materials now commonly import separate per-texture matrices instead of a single one even if they're all the same because that makes the plugin implementation much simpler. However, existing code that assumes there's just one matrix would get broken because textureMatrix() would not return something else. By changing that to return a common matrix if present and falling back to the global one we can preserve the original behavior.	6 years ago
Vladimír Vondruš	79e8fa0b05	Trade: add a query for packed clearcoat factor/roughness texture. glTF, always some surprise waiting around the corner.	6 years ago
Vladimír Vondruš	a2b1fa0572	Trade: properly consider texture IDs when checking for packing.	6 years ago
Vladimír Vondruš	c2942ce7ac	Trade: material packing queries definitely check for different IDs, right? Err, nope. Not a single one of them.	6 years ago
Vladimír Vondruš	44f67e7748	Trade: rethink common material texture coordinate transform/sets. There's actually a lot of code involved in checking if all textures use the same transform or coordinate set, especially when considering all fallback variants and potential future expansion with separate texture offset/scale/rotation attributes. A lot of the complexity was thus hidden in plugin implementations, which were each trying to find a common value for all textures to save the user from doing the same. All that code can now be removed and left up to the material APIs themselves -- now it's just about checking hasCommonTextureTransformation() and then retrieving that one common transformation, independently on how the material actually defines it.	6 years ago
Vladimír Vondruš	b1a719d67a	sceneconverter: list textures in --info.	6 years ago
Vladimír Vondruš	81f5468b65	Trade: custom material attribs can start with non-letters as well. Becase $assimp ?does +that.	6 years ago
Vladimír Vondruš	829e9b6d0f	Trade: add forgotten OcclusionTextureStrength attribute. Whoops, again.	6 years ago
Vladimír Vondruš	b3a848c0d6	Trade: sigh, MSVC 2015, again.	6 years ago
Vladimír Vondruš	baa23ffd10	Trade: and you, MSVC 2015, need a special place in hell.	6 years ago
