description	Cross-platform graphics theory and rendering engineering: shader math, optical physics, light transport, BRDF/BSDF models, Monte Carlo sampling, PBR, coordinate systems, numerical stability, neural rendering (3DGS, NeRF), ReSTIR/DDGI real-time GI, spectral rendering, differentiable rendering (Mitsuba 3), GPU compute advances (mesh shaders, work graphs, bindless), volumetric rendering, advanced sampling (blue noise, path guiding), color science (ACEScg, Oklab, AgX, HDR), temporal techniques (DLSS/FSR/XeSS), and WebGPU. Use when working on rendering math, cross-platform shader code (Vulkan, WebGPU, GLSL, HLSL, WGSL), validating physical correctness, solving graphics math problems, implementing neural rendering pipelines, or optimizing GPU-driven rendering. For Apple Metal specifically, use the metal skill.

Graphics

Overview

• Apply rigorous math and physics checks before writing rendering code.
• Use the analysis protocol and validation checklists in references/guidelines.md.
• Consult references/sota.md for state-of-the-art techniques (2023–2026) including neural rendering, ReSTIR, spectral rendering, differentiable rendering, and modern GPU compute.

Workflow

1. Read references/guidelines.md for the required analysis protocol, forbidden patterns, and foundational formulas.
2. If the task involves SOTA techniques (neural rendering, ReSTIR, real-time GI, spectral, differentiable rendering, GPU-driven pipelines, temporal upscaling, WebGPU, advanced materials, volumetric rendering, advanced sampling, or color science), also read references/sota.md for the relevant section.
3. Output the <graphics_analysis> block exactly as specified before any rendering code.
4. Make coordinate systems, units, and numerical stability explicit in explanations and code.
5. Verify physical plausibility (energy conservation, reciprocity) and edge cases.
6. Follow the naming, structure, and documentation standards from the guidelines.

When to Read Which Reference

• Always read references/guidelines.md — it contains the analysis protocol, forbidden patterns, core formulas, and validation checklists that apply to ALL graphics work.
• Read references/sota.md when the task involves any of these keywords or domains: neural rendering, gaussian splatting, 3DGS, NeRF, ReSTIR, DDGI, radiance caching, Lumen, real-time GI, ray tracing hardware, denoising (SVGF, NRD), OpenPBR, MaterialX, spectral rendering, hero wavelength, differentiable rendering, Mitsuba, mesh shaders, work graphs, nanite, visibility buffer, GPU-driven, bindless, volumetric rendering, null-tracking, cloud rendering, blue noise, path guiding, PMJ, EARS, color science, ACEScg, AgX, Oklab, HDR, PQ, tonemapping, temporal upscaling, DLSS, FSR, XeSS, frame generation, WebGPU, WGSL.
