@plasius/gpu-worker

A WebGPU worker runtime that builds on @plasius/gpu-lock-free-queue to schedule WGSL workloads like ray tracing, physics, and acoustics.

Apache-2.0. ESM + CJS builds. WGSL assets are published in dist/.

Install

npm install @plasius/gpu-worker

Usage

import { assembleWorkerWgsl, loadWorkerWgsl } from "@plasius/gpu-worker";

const workerWgsl = await loadWorkerWgsl();
const shaderCode = await assembleWorkerWgsl(workerWgsl);
// Pass shaderCode to device.createShaderModule({ code: shaderCode })

What this is

• A minimal GPU worker layer that combines a lock-free queue with user WGSL jobs.
• A helper to assemble WGSL modules with queue helpers included.
• A reference job format for fixed-size job dispatch (u32 indices).

Demo

The demo enqueues ray tracing tile jobs on the GPU and renders a simple scene. Install dependencies first so the lock-free queue package is available for the browser import map.

npm install
python3 -m http.server

Then open http://localhost:8000/demo/.

Build Outputs

npm run build emits dist/index.js, dist/index.cjs, and dist/worker.wgsl.

Files

• demo/index.html: Loads the ray tracing demo.
• demo/main.js: WebGPU setup, enqueue, and ray tracing kernel.
• src/worker.wgsl: Worker entry points that dequeue jobs and run a ray tracer.
• src/index.js: Helper functions to load/assemble WGSL.

Job shape

Jobs are u32 indices into a fixed workload array (tiles, particles, etc). Keep job data fixed-size; use indices into a separate payload buffer for variable payloads.
