# WebGPU Demo (Rust, in your browser)

A live demo of the Rust `kataglyphis_webgpu_renderer` crate
(`ExternalLib/Kataglyphis-RustProjectTemplate/crates/webgpu_renderer`),
compiled to WebAssembly and running on the WebGPU API — the same renderer
that runs natively on Vulkan/DX12/Metal. It renders a glTF scene with the
metallic-roughness PBR pipeline, directional shadow mapping (3×3 PCF), and
ACES tonemapping from an HDR target.

Requires a WebGPU-capable browser (Chrome/Edge 113+, Firefox 141+).

## About

- **Features shipped**: the renderer is well past the original milestones —
  the authoritative per-feature status (IBL, skybox, animation/skinning/morph
  targets, egui overlay, bloom, SSAO, auto-exposure, LOD, GPU occlusion
  culling, and more) is `docs/webgpu-renderer-roadmap.md` in the repository.
- **Rebuild the demo**: `Scripts/Linux/docs-build-web.sh` compiles
  `kataglyphis_webgpu_renderer` to wasm32, runs `wasm-bindgen`, and refreshes
  this folder before Sphinx runs; the CI docs deploy runs it automatically,
  so the deployed demo always tracks the current renderer.
