MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

WebGLTransformFeedback

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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();
