OES_element_index_uint - Web APIs 编辑

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 type parameter now accepts gl.UNSIGNED_INT.

Examples

var ext = gl.getExtension('OES_element_index_uint');

gl.drawElements(gl.POINTS, 8, gl.UNSIGNED_INT, 0);
