WEBGL_lose_context.loseContext()

The WEBGL_lose_context.loseContext() method is part of the WebGL API and allows you to simulate losing the context of a WebGLRenderingContext context.

It triggers the steps described in the WebGL specification for handling context lost. The context will remain lost until WEBGL_lose_context.restoreContext() is called.

Syntax

gl.getExtension('WEBGL_lose_context').loseContext();

Examples

With this method, you can simulate the webglcontextlost event:

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');

canvas.addEventListener('webglcontextlost', function(e) {
  console.log(e); 
}, false);

gl.getExtension('WEBGL_lose_context').loseContext();

// WebGLContextEvent event with type "webglcontextlost" is logged.
