This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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:
WebGL2RenderingContext.createTransformFeedback()WebGL2RenderingContext.deleteTransformFeedback()WebGL2RenderingContext.isTransformFeedback()WebGL2RenderingContext.bindTransformFeedback()WebGL2RenderingContext.beginTransformFeedback()WebGL2RenderingContext.endTransformFeedback()WebGL2RenderingContext.pauseTransformFeedback()WebGL2RenderingContext.resumeTransformFeedback()WebGL2RenderingContext.transformFeedbackVaryings()WebGL2RenderingContext.getTransformFeedbackVarying()WebGLTransformFeedback objectin this example, gl must be a WebGL2RenderingContext. WebGLTransformFeedback objects are not available in WebGL 1.
var transformFeedback = gl.createTransformFeedback();
