Claim One:
1. In a computer having a video display and a storage, a method of hazing a plurality of polygons, comprising the steps of: selecting one of the polygons from the storage; calculating a haze value as: EQU haze value=(z*kval)/dimval where z is the distance between a camera position and the selected polygon, kval is a constant, and dimval is the distance for full hazing; calculating a shade value as the dot product of a sun vector and the normal to the polygonal plane; indexing a dither table with the haze and shade values for dither color offsets; adding a base color to the dither color offsets for dither colors; determining a dither pattern of dither colors based on the position of the selected polygon; and drawing the selected polygon on the video display using the dither pattern.
