Yes! OpenGL can receive data from OpenCV that you can use to draw to a dynamic OpenGL texture! It just so happens that I'm doing something similar (using OpenGL and OpenCV in a project, but using dual windows on MacOSX). If you are storing your OpenCV image data in an IplImage structure, you can write IplImage::imageData to your texture (assuming you've created it already) using glTexSubImage2D. Keep in mind that the pixel format is BGR, so you want to use GL_BGR_EXT.
This should do the trick. If it's not what you need, sorry if I misinterpreted what you were asking for. Either way, let me know and I'll try to come up with a different solution if that's what you need.
