Abstract
A method and apparatus in a data processing system for generating a two dimensional display of a three dimensional object. Data is received representing the three dimensional object. Back-face culling is performed using a data structure, wherein the data structure includes a set of predetermined visibility data derived from the results of dot products of normal vectors with eye vectors. The two dimensional display of the three dimensional object is generated using results of the back-face culling.
