From 8fb2ff458ba579dba08bfdf57d043ad158b5db07 Mon Sep 17 00:00:00 2001 From: Jeroen Bakker Date: Mon, 17 Jan 2022 14:32:03 +0100 Subject: GPUShaderCreateInfo for interface abstraction This is a first part of the Shader Create Info system could be. A shader create info provides a way to define shader structure, resources and interfaces. This makes for a quick way to provide backend agnostic binding informations while also making shader variations easy to declare. - Clear source input (only one file). Cleans up the GPU api since we can create a shader from one descriptor - Resources and interfaces are generated by the backend (much simpler than parsing). - Bindings are explicit from position in the array. - GPUShaderInterface becomes a trivial translation of enums and string copy. - No external dependency to third party lib. - Cleaner code, less fragmentation of resources in several libs. - Easy to modify / extend at runtime. - no parser involve, very easy to code. - Does not hold any data, can be static and kept on disc. - Could hold precompiled bytecode for static shaders. This also includes a new global dependency system. GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...). This patch already migrated several builtin shaders. Other shaders should be migrated one at a time, and could be done inside master. There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional directive for linting shaders to increase turn around time. What is remaining: - pyGPU API {T94975} - Migration of other shaders. This could be a community effort.
