Use when building or reviewing Canvas 2D, Three.js/WebGL, React Three Fiber, GLSL shaders, ShaderToy-to-WebGL adaptation, 2D/3D visualization, game rendering, animation loops, GPU resource cleanup, or rendering performance. Do not use for standard DOM UI, charts already covered by a chart library, or non-graphical performance work; Chinese triggers include Canvas, Three.js, WebGL, GLSL, Shader, 3D, data visualization, games.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Canvas and Three.js ## Purpose Enable high-performance 2D/3D graphics rendering in the browser. ## Procedure 1. First select the rendering layer: DOM for standard UI; Canvas 2D for simple 2D graphics/signatures/particles; Three.js/WebGL for 3D models, spatial interactions and complex particles; React Three Fiber for declarative 3D in React projects. 2. Define stable size, DPI adaptation, and resize behavior for the render container; Canvas does not automatically scale cleanly with CSS. 3. The animation loop uses `requestAnimationFrame`, which is paused when it is invisible or has no changes, and canceled when it is uninstalled. 4. Three.js must release geometry/material/texture/renderer and remove event listeners and observers. 5. Shader/WebGL tasks first identify whether it is an SDF, ray marching, noise, particle, post-processing, multipass or debugging issue, and then decide whether native WebGL2, Three.js ShaderMaterial or R3F is required. 6. Check the GLSL version, entry function, varying/in-out, texture API, uniform usage and function declaration order when adapting to WebGL2 to avoid white screen leaving only console errors. …

How to install
mdr add bovinphang/frontend-craft/fec-canvas-threejs@sha256:8fcdcb41f638830cThe line at the top of this page pins the label git:20260611.9d7f5e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
