This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The WebGLRenderingContext
.commit()
method pushes frames back to the original HTMLCanvasElement
, if the context is not directly fixed to a specific canvas.
void WebGLRenderingContext.commit()
var htmlCanvas = document.createElement('canvas'); var offscreen = htmlCanvas.transferControlToOffscreen(); var gl = offscreen.getContext('webgl'); // ... some drawing using the gl context ... // Push frames back to the original HTMLCanvasElement gl.commit();
Currently drafted as a proposal in the OffscreenCanvas specification.
