Yawn
Yawn Core is two things: a generic structure-of-arrays arena in a SharedArrayBuffer, and a Rust render graph that turns externally supplied WGSL into an up-front WebGPU loadout.
JSO or FXNode → AST → S-expression → worker messages → Rust/WebGPU
↑
any thread → direct shared row writes ─────────────┘
The arena starts with only one eight-float signals row for frame timing and render invalidation. Messages create or delete other { name, rows, stride, format } arrays, allocate named slots, compile graphs, switch loadouts, and control render pacing. Existing render data is changed by writing f32, u32, or i32 rows directly, then setting the shared-data dirty signal. Allocations are 64-byte aligned, row strides are multiples of 16 bytes, and compatible non-overlapping transient textures share physical allocations.
WGSL, pipelines, glTF import, and conventional mesh/camera/material handles live in addons/; core contains no shader or scene model.
Run the Go website, in-memory package server, SQLite-backed playground, and tutorial:
npm run server
The server rebuilds @yawn/core and @yawn/handles at startup and serves the public CDN modules at
https://yawn.heaust.org/pkg/core.js and https://yawn.heaust.org/pkg/handles.js. Their workers and
WASM stay on the CDN automatically, so applications only import the module URLs. The complete editor is at /playground; saved revisions use
/playground/{id}/{revision} URLs. Set PORT or YAWN_DATABASE to override the default port and
server/data/yawn.db database path.
Run the previous VitePress documentation site with npm start.
Run npm run coredocs for the raw worker-message, shared-memory, and render-graph reference intended for custom handles, editors, and direct SAB clients.
