Abstract

A new algorithm to recognize occluder silhouette to generate shadow volume with some improvement of the traditional shadow volume algorithm is proposed. We named the new algorithm as Extended Edge Silhouette Detection (EESD). Silhouette detection is one of the expensive processes of shadow volumes. The triangular algorithm and visible-non-visible algorithm that are famous algorithms to detect the outline of occluder are renewed. An accurate comparison between these algorithms and a new algorithm has been done. The algorithm is to detect silhouette and decreases the cost of implementation of shadow volume. The obtained results confirm superiority of the proposed algorithm in terms of processing time compared to the previously used traditional algorithms. The last shadow volume algorithm using stencil buffer is rewritten and an algorithm for shadow volume with silhouette detection together is proposed.
