POV-Ray is a ray tracing program which calculates individual rays to
render an image.
I am not sure but suspect the Maya and Houdini don't do ray tracing at
all and use openGL to render images, which is what a 3D card designed
As for the speed, OpenGL is much less CPU intensive than raytracing
even without GPU.
