WebGLRenderingContext.getSupportedExtensions()
The WebGLRenderingContext.getSupportedExtensions()
method returns a list of all the supported WebGL extensions.
Syntax
JavaScript
Copy Code
<var>gl</var>.getSupportedExtensions();
Return value
An Array
of strings with all the supported WebGL extensions.
Examples
JavaScript
Copy Code
var canvas = document.getElementById("canvas"); gl = canvas.getContext("webgl"); var extensions = gl.getSupportedExtensions(); // Array [ "ANGLE_instanced_arrays", "EXT_blend_minmax", ... ]
See also the WebGLRenderingContext.getExtension()
method to get a specific extension object.
