Revision 1028516 of WebGLVertexArrayObjectOES

<div>{{APIRef("WebGL")}}</div>

<p>The <strong><code>WebGLVertexArrayObjectOES</code></strong> interface is part of the <a href="/en-US/docs/Web/API/WebGL_API">WebGL</a> {{domxref("OES_vertex_array_object")}} extension and represents vertex array objects (VAOs) pointing to vertex array data and providing names for different sets of vertex data.</p>

<p>WebGL extensions are available using the {{domxref("WebGLRenderingContext.getExtension()")}} method. For more information, see also <a href="/en-US/docs/Web/API/WebGL_API/Using_Extensions">Using Extensions</a> in the <a href="/en-US/docs/Web/API/WebGL_API/Tutorial">WebGL tutorial</a>.</p>

<div class="note">
<p><strong>Availability:</strong> 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 and this interface is named {{domxref("WebGLVertexArrayObject")}}.</p>
</div>

<p>When working with <code>WebGLVertexArrayObjectOES</code> objects, the following methods of the {{domxref("OES_vertex_array_object")}} extension are useful:</p>

<ul>
 <li>{{domxref("OES_vertex_array_object.createVertexArrayOES()", "ext.createVertexArrayOES()")}}</li>
 <li>{{domxref("OES_vertex_array_object.deleteVertexArrayOES()", "ext.deleteVertexArrayOES()")}}</li>
 <li>{{domxref("OES_vertex_array_object.isVertexArrayOES()", "ext.isVertexArrayOES()")}}</li>
 <li>{{domxref("OES_vertex_array_object.bindVertexArrayOES()", "ext.bindVertexArrayOES()")}}</li>
</ul>

<pre class="brush: js">
var ext = gl.getExtension("OES_vertex_array_object");
var vao = ext.createVertexArrayOES();
ext.bindVertexArrayOES(vao);

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