TSL (Three.js Shading Language) and WebGPU shader development with Three.js. Write, review, and refactor GPU shaders using TSL's node system, compute shaders, and WebGPU renderer. Use when: (1) Setting up WebGPURenderer in Three.js or React Three Fiber, (2) Writing TSL shaders with Fn, uniform, varying, texture, (3) Creating or modifying node materials (MeshStandardNodeMaterial, SpriteNodeMaterial, etc.), (4) Using positionNode, colorNode, normalNode or other material nodes, (5) Writing compute shaders with instancedArray, storage, compute(), computeAsync(), (6) Building particle systems with sprite and SpriteNodeMaterial, (7) Post-processing with TSL (pass, bloom, fxaa, PostProcessing class), (8) Porting GLSL shaders to TSL or WGSL, (9) Using wgslFn, glslFn, or code() for native shader code, (10) Working with StorageTexture, textureStore, or GPU buffers, (11) Implementing instanced meshes with compute pipeline, (12) Any Three.js WebGPU or TSL related development.
