Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.isTransformFeedback() method of the WebGL 2 API returns true if the passed object is a valid WebGLTransformFeedback object.
Syntax
GLboolean gl.isTransformFeedback(transformFeedback);
Parameters
transformFeedback- A
WebGLTransformFeedbackobject to test.
Return value
A GLboolean indicating whether the given object is a valid WebGLTransformFeedback object (true) or not (false).
Examples
gl must be a WebGL2RenderingContext. WebGLTransformFeedback objects are not available in WebGL 1.
var transformFeedback = gl.createTransformFeedback(); // ... gl.isTransformFeedback(transformFeedback);
