title: Tutorial on OpenGL combined with OpenCV for Computer Vision
body: <p>Does anybody know a good tutorial or documentation that deals with mixing <code>OpenCV</code> and <code>OpenGL</code> in C++, related with <code>Computer Vision</code> and 3D rendering?</p>
  
  <p>I want to create virtual scenarios with objects and then find <code>object's 3D poses</code> using OpenCV, so I can compare with the known OpenGL position but I didn't find much "quality" information so far. For example, I would need the intrinsic parameters of the opengl camera in order to use OpenCV for detecting objects in 3D world, etc.</p>
