I wanted to process a image by OpenCV. It's generated by OpenGL. Firstly, I saved this image in my hard disk and read it with OpenCv, but I found it inefficient.
So I want to find an interface from OpenGL to OpenCV so that I don't need to save the image to my hard disk.
The function "load3dDataToGL" is not what I want. I just want to load image from OpenGL.
