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();
