Displaying video from OpenCV to OpenGL

Hello, I have a program written in OpenCV which captures video from webcam and displays it. I would need to use some functionalities of OpenGL because after image processing, I need to do some 3D modeling, shading as well.
My first question is: Can I use OpenCV and OpenGL at the same time?
My second question is: Is it possible the video displayed in OpenCV to be displayed in OpenGL?

Please provide me some suggestions.
Thanks in advance.
