I was trying to link a texture buffer in openGL with a cuda array which allows me to pass
my calculated results to openGL to be displayed later on the screen.
However, I found the cuFFT is paralyzed after
cudaGraphicsGLRegisterImage(&… , …, GL_TEXTURE_2D, cudaGraphicsRegisterFlagsNone) is applied.
Not sure if it is a driver conflict / library conflict or any other possible mistake.
Does any one have a clue?
(I debugged my code line by line to find out cudaGraphicsGLRegisterImage is the line paralyze cuFFT.)
FYI I am using CUDA 5.0 / openGL 4.3on Nvidia GTX 460 SE.
