OES_vertex_array_object

The OES_vertex_array_object extension is part of the WebGL API and provides vertex array objects (VAOs) which encapsulate vertex array states. These objects keep pointers to vertex data and provide names for different sets of vertex data.

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 and the constants and methods are available without the "OES" suffix.

Constants

This extension exposes one new constant, which can be used in the gl.getParameter() method:

ext.VERTEX_ARRAY_BINDING_OES
Returns a WebGLVertexArrayObject object when used in the gl.getParameter() method as the pname parameter.

Methods

This extension exposes four new methods.

ext.createVertexArrayOES()

Creates a new WebGLVertexArrayObject.

ext.deleteVertexArrayOES()

Deletes a given WebGLVertexArrayObject.

ext.isVertexArrayOES()

Returns true if a given object is a WebGLVertexArrayObject.

ext.bindVertexArrayOES()

Binds a given WebGLVertexArrayObject to the buffer.

Examples

var oes_vao_ext = gl.getExtension('OES_vertex_array_object');
var vao = oes_vao_ext.createVertexArrayOES();
oes_vao_ext.bindVertexArrayOES(vao);

// ...
// calls to bindBuffer or vertexAttribPointer 
// which will be "recorded" in the VAO
// ...
