Convert OpenGL texture to OpenCV Mat

Question

Is there any way to convert OpenGL's GLuint texture type to OpenCV's cv::Mat ?

I have got just the oposite function, texture2opencvMat, if you are interested stackoverflow.com/q/9126002/744859 — Jav_Rock

You may want to take a look at this question which asks about converting from glReadPixels into a cv::Mat, which is exactly the same problem when using glGetTexImage instead of glReadPixels.

My answer to this question explains how to directly read the texture data into the cv::Mat's storage with all possible pitfalls (like padding, color ordering, ...).
