How do I use graphics functions in CUDA?

Question

I want to use basic functions like putpixel, initwindow in CUDA. How do I do it?

Answer 1

I would rather use the CUDA - OpenGL interop to visualize results from CUDA, see eg http://3dgep.com/opengl-interoperability-with-cuda/

Answer 2

CUDA cannot output directly to a window backbuffer. However, you can still use CUDA to write to a texture or a buffer and then use the results to visualize it in OpenGL. For a thorough example on how to do this, please refer to this project:
