Abstract

This article proposes a fast shadow generation algorithm using space subdivision. Space is divided into 6 segments and every polygon in the scene is determined whether it is the self-shadows or the projected shadows in each segment. The method is effective for rapid generation of realistic half-tone images with shadows. Algorithm
