OES_element_index_uint extension

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The OES_element_index_uint extension is part of the WebGL API and adds support for gl.UNSIGNED_INT types to WebGLRenderingContext.drawElements().

WebGL extensions are available using the WebGLRenderingContext.getExtension() method. For more information, see also Using Extensions in the WebGL tutorial.
