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 WebGL2RenderingContext.pauseTransformFeedback() method of the WebGL 2 API pauses a transform feedback operation.
Syntax
void gl.pauseTransformFeedback();
Parameters
None.
Return value
None.
Examples
var transformFeedback = gl.createTransformFeedback(); gl.bindTransformFeedback(gl.TRANSFORM_FEEDBACK, transformFeedback); gl.beginTransformFeedback(gl.TRIANGLES); gl.pauseTransformFeedback(); //... gl.resumeTransformFeedback(); gl.drawArrays(gl.TRIANGLES, 0, 3); gl.endTransformFeedback();
