Abstract:
A method and system may include a hardware texture unit having logic to receive parameters of a view ray for a pixel of a graphical scene, and determine an illumination of the view ray. The illumination, which could indicate an in-scatter illumination percentage for the view ray, may be passed to a software module such as a pixel shader for rendering of the pixel.
