Build a single HTML visualizer for particles, fractals, simulations, or data. It moves heavy calculations into a Web Worker, a background browser process, and draws on a canvas while targeting smooth 60fps rendering.

A real-time data/particle/simulation visualizer whose heavy compute runs in a Web Worker (off the main thread), optionally sharing memory with the UI via SharedArrayBuffer, and renders to a canvas at 60fps. Produced as a single self-contained `index.html`. Use when the brief asks for a "web worker", "simulation", "particle system", "physics", "off-main-thread", "fractal", "real-time compute", or "audio/data visualizer". OpenDesign serves this in powered-preview mode so Workers and SharedArrayBuffer actually work.

Produce a single self-contained index.html that moves heavy per-frame compute into a Web Worker and renders the result to a canvas, keeping the main thread at a smooth 60fps.
OpenDesign detects new Worker( / SharedArrayBuffer / OffscreenCanvas and renders this file in powered preview — a cross-origin-isolated iframe with allow-same-origin. That means external and blob Web Workers construct successfully, SharedArrayBuffer is defined (crossOriginIsolated === true), and importScripts works. In the old opaque sandbox all three failed; here they just work.

└── example.html ← a working 12k-particle SharedArrayBuffer sim (READ FIRST)
Read example.html. Note the split: the worker integrates positions each tick; the main thread only reads + draws. It feature-detects crossOriginIsolated and uses a SharedArrayBuffer for zero-copy when available, falling back to a transferable postMessage copy otherwise. Always ship that fallback so the artifact still animates if isolation is off.
Pick ONE compute-bound job worth offloading:
ImageData buffer.index.htmlBlob + URL.createObjectURL (inline its source), or embed it as a data: URL.SharedArrayBuffer to the worker, and read the same Float32Array/Uint8ClampedArray view while drawing. Guard on typeof SharedArrayBuffer !== 'undefined' && crossOriginIsolated.postMessage a transferable ArrayBuffer each frame.OffscreenCanvas + canvas.transferControlToOffscreen() to render inside the worker for the heaviest scenes.SharedArrayBuffer path engages when crossOriginIsolated is true; postMessage fallback engages otherwise — verify BOTH branches degrade cleanly.还没有评价。欢迎分享你的使用感受。
