Render a 8bit grayscale image with OPENGL Do I need do this or not?

Hello everyone,

Currently, I’m working in an application which process an image (8 bit gray scale) with kernels (CUDA), after this I need render it (i have the data in device memory). Do i need to use OPENGL? what a want to know is if it is faster using OPENGL?..

My image is 2048*2048. :confused:

Thanks!

I believe the Sobel filter SDK sample uses OpenGL and displays grayscale. Check it out.
