Abstract

In this paper, we propose an effective bump mapping algorithm that utilizes the reference space with the polarcoordinate system and also propose a new hardware architecture associated with the proposed bump mapping algorithm. The proposed architecture reduces thecomputations to transform the vectors from the object space into the reference space by using a new vector rotation method. It also reduces thecomputations for the illuminationcalculation by using the law ofcosine. compared with the previous approaches, the proposed architecture reduces multiplication operations up to 78%.
