I do some calculation on a 2D float array on the GPU and would like to display the results of the computation via OpenGL. I’d like each float value to be associated with a grey-value in the display.
I know that there are a lot of OpenGL Interop examples in the SDK but I find them very confusing and don’t really know how to approach the problem. Could someone with more OpenGL experience than myself maybe outline the steps necessary to do this or point me to an example where something similar is done?
Any help would be greatly appreciated.
