   OpenGL Image processing
  I have written some code that provides me with the raw data of video frames and I want to manipulate the pixel data of each frame.I am using OpenGL (in Qt) and C++.After manipulating the video frame I want to render it using OpenGL.I have researched that I probably should use FBOs to render the data, but I don't quite know how it all works.Do I have to copy the video frame into a texture and then use that texture in combination with the FBO? How would I set that up?I have found some tutorials about how to use FBOs in 3D, but they don't really explain the mechanics about it. I only need to set up a 2D environment to display the video frames, don't I.Can anyone point me to some tutorials that actually explain things in detail and use plain OpenGL?   
  I believe it was in GPU Gems 1 (might be 2) that had a framework for image processing on the GPU.  They're both freely available on http://developer.nvidia.comFound it:  http://http.developer.nvidia.com/GPUGems/gpugems_ch27.htmlCheers, Bob
