ABSTRACT:
A method of generating a computer image wherein secondary raytrace vectors are calculated for the image after the image is rendered using rasterization. The secondary raytrace vectors are based on virtual camera angles that are stored during the rasterization process. The raytrace vectors can be calculated using the same processor as the rasterization, thereby providing greater consistency in the image. A metaprogrammed shader can also be applied to the generated image, wherein the shader uses the same processor as the raytrace and rasterization steps. The metaprogrammed shader allows the shader algorithm to be segmented for streamlined processing by the processor.
