{{APIRef("WebGL")}}
The OES_element_index_uint extension is part of the WebGL API and adds support for gl.UNSIGNED_INT types to {{domxref("WebGLRenderingContext.drawElements()")}}.
WebGL extensions are available using the {{domxref("WebGLRenderingContext.getExtension()")}} method. For more information, see also Using Extensions in the WebGL tutorial.
[!NOTE] This extension is only available to {{domxref("WebGLRenderingContext", "WebGL1", "", 1)}} contexts. In {{domxref("WebGL2RenderingContext", "WebGL2", "", 1)}}, the functionality of this extension is available on the WebGL2 context by default.
This extension extends {{domxref("WebGLRenderingContext.drawElements()")}}:
type parameter now accepts gl.UNSIGNED_INT.const ext = gl.getExtension("OES_element_index_uint");
gl.drawElements(gl.POINTS, 8, gl.UNSIGNED_INT, 0);
