2022-04-14 | GPU: Make nodetree GLSL Codegen render engine agnostic | Clément Foucault | |
This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl` files. It defines a clear interface to evaluate the closure nodes leaving more flexibility to the render engine. Some of the long standing workaround are fixed: - bump mapping support is no longer duplicating a lot of node and is instead compiled into a function call. - bump rewiring to Normal socket is no longer needed as we now use a global `g_data.N` for that. Closure sampling with upstread weight eval is now supported if the engine needs it. This also makes all the material GLSL sources use `GPUSource` for better debugging experience. The `GPUFunction` parsing now happens in `GPUSource` creation. The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type agnostic. Is has also been rewritten in C++. This patch changes a view behavior for EEVEE: - Mix shader node factor imput is now clamped. - Tangent Vector displacement behavior is now matching cycles. - The chosen BSDF used for SSR might change. - Hair shading may have very small changes on very large hairs when using hair polygon stripes. - ShaderToRGB node will remove any SSR and SSS form a shader. - SSS radius input now is no longer a scaling factor but defines an average radius. The SSS kernel "shape" (radii) are still defined by the socket default values. Appart from the listed changes no other regressions are expected. | |||

Also use doxy style function reference `#` prefix chars when referencing identifiers. | |||
2020-07-30 | EEVEE: GLSL refactor/cleanup | Clément Foucault | |
- add the use of DRWShaderLibrary to EEVEE's glsl codebase to reduce code complexity and duplication. - split bsdf_common_lib.glsl into multiple sub library which are now shared with other engines. - the surface shader code is now more organised and have its own files. - change default world to use a material nodetree and make lookdev shader more clear.

2019-08-30 | GPU: Split gpu_shader_material into multiple files. | OmarSquircleArt | |
This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch. Reviewers: brecht Differential Revision: https://developer.blender.org/D5616 |
