Hi,
I actually don't really know where I should post this question so please forgive me if it's in the wrong discussion section. Basically, I'm developing a CUDA program to calculate the FFT power spectrum of a series of images which are captured continuously and want to show the power spectrum in a window at the same time. I'm not what I could use to draw the power spectrum. I thought about OpenGL but I really only know how to draw in 3D rather than 2D. Or is there anything else that I could use? Thanks in advance for any help.

Your using Nvidia CUDA so you might consider Direct Compute instead which is a Windows API built on top of CUDA like CUDA-C is but it also supports non-vendor specific APIs so you could run on AMDs D3D 10+ hardware as well. That said, Direct Compute has access to all the Direct3D resources where you could use a ID3D10Texture2D to draw your FFT power spectrum and then draw it to the window. Since your dabbling in CUDA you must have a good programming knowledge base but if you have not done Windows programming, Direct3D and Direct Compute all this together would be very challenging.

Thank you so much. I'll have a good look at them and see how it goes.
