1. A Computer system for displaying two dimensional representation of three dimensional objects in response to a plurality of graphics drawing orders, said graphics drawing orders including object attributes, said computer system including processor means, the system comprising: first memory means for storing pixel data including a light intensity value for each of a plurality of pixels, said pixel data being generated by said processor means in response to said graphics drawing orders; second memory means for storing a polarization value representing relative light polarization to be applied to the light intensity value, said memory means storing a polarization value including a polarization angle and a polarization degree determined on a pixel by pixel basis, for each of said plurality of pixels; processor means for modifying said light intensity value of one or more of said plurality of pixels in said first memory means using a read-modify-write pixel operation based on said light intensity value and said polarization value for each pixel and for modifying said polarization value of said one or more pixels iteratively in response to a second and subsequent graphics drawing order and a display device for displaying said plurality of pixels.
