Thanks for the quick reply. I do have an RTT camera writing to FBO which then gets processed by CUDA and passed to a full screen quad, I just wanted to replace the CUDA bit with OpenCL for increased compatibility. I do believe I need CUDA or OpenCL vs shaders for my post processing since I need to do things like histogram equalization that would be prohibitively difficult with shaders (at least I think it would be).
