ABSTRACT:
A method and apparatus for generating pixel shading values in a computer controlled display system. Generally, the apparatus is embodied in a rendering pipeline, where each stage of the pipeline performs a particular pixels shading function, so that pixels are shaded in a distributed and direct fashion. The method of the present invention includes the steps of: deriving a pixel interpolation value from an object description, providing a first and second shading parameters and the pixel interpolation value to a first shader, generating the first shading value for the pixel, providing second and third shading parameters and the pixel interpolation value to a second shader and generating second shading value for the pixel.
