WebGLTransformFeedback

The WebGLTransformFeedback interface is part of the WebGL 2 API and enables transform feedback, which is the process of capturing primitives generated by vertex processing. It allows to preserve the post-transform rendering state of an object and resubmit this data multiple times.

When working with WebGLTransformFeedback objects, the following methods of the WebGL2RenderingContext are useful:

Examples

Creating a WebGLTransformFeedback object

in this example, gl must be a WebGL2RenderingContext. WebGLTransformFeedback objects are not available in WebGL 1.

var transformFeedback = gl.createTransformFeedback();
