Adds a self-contained browser playground (editor + canvas + console + REPL) around the Emscripten WebGPU build, plus the engine fixes required to render: - JS<->Squirrel bridge (apply/eval/read/pause) and Emscripten 6 exports - soft hot-reload via load.nut handle_change with __pg state preservation - fix Uint16 index buffer byte sizes in SetIndexBuffer calls - fix dangling GbufferSlot/SceneColorSlot gpuHandle pointers (std::move bug) - fallback shadow depth texture when no shadow map is configured - fix WGSL syntax (mod/ivec2) and default shadow sampler maxAnisotropy - serve_webgpu.py COOP/COEP server and playground docs/demos/assets

"""Serve the EVEngine WebGPU build directory with cross-origin isolation.
|
|
|
|
The Emscripten build runs the engine on pthreads and needs SharedArrayBuffer,
|
|
so the page MUST be served with COOP/COEP headers -- opening eve.html via
|
|
file:// will not work. This server adds those headers plus no-store caching so
|
|
rebuilt eve.js / eve.wasm / eve.data are always picked up.
|
|
|
|
Usage (from the repo root):
|
|
python scripts/serve_webgpu.py # serves build/webgpu-web/src/engine :8090
|
|
python scripts/serve_webgpu.py <engine-dir> [port]
