WebGLRenderingContext.commit()

このロケールの翻訳が存在しないため、英語バージョンのコンテンツを表示しています。 Help us translate this article!

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.

Syntax

void WebGLRenderingContext.commit()

Examples

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();

Specifications

Currently drafted as a proposal in the OffscreenCanvas specification.
