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.
Availability: This extension is only available to WebGL1 contexts. In WebGL2, the functionality of this extension is available on the WebGL2 context by default.
Extended methods
This extension extends WebGLRenderingContext.drawElements():
- The
typeparameter now acceptsgl.UNSIGNED_INT.
Examples
var ext = gl.getExtension("OES_element_index_uint");
gl.drawElements(gl.POINTS, 8, gl.UNSIGNED_INT, 0);
