Abstract
The present invention conducts rendering processing according to a prescribed priority relating to each polygon attribute. For example, rendering for semi-transparent polygons is conducted after rendering for opaque polygons. By this means, it is possible to carry out rendering for semi-transparent polygons reliably. Furthermore, rendering for polygons containing transparent portions is conducted after rendering for polygons not containing transparent portions. By this means, it is possible to reduce rendering processing for polygons containing transparent portions, as far as possible. Moreover, rendering processing is carried out for all background polygons together. Thereby, it is possible to carry out suitable depth cue processing for polygons positioned in the far distance of the screen.
