In this paper, we proposed a low complexity subdivision algorithm to approximate Phong shading. It is a combination of a subdivision scheme using forward difference and a recovery scheme to prevent rasterization anomaly. Dual space subdivision, triangle filtering and variable sharing schemes are also proposed to reduce the computation. Compared with the conventional recursive subdivision shading algorithm,...
Energy consumption and routing fidelity are two of the most concerns in developing protocols and algorithms for wireless sensor networks. GAF is one of the most popular algorithms which can not only conserve energy but also keep the routing fidelity. GAF conserves energy by using geographic location information to identify the equivalence between nodes and then turn off their radio accordingly. However,...
An innovative multi-mode depth buffer compression algorithm has been developed for 3D graphics system. It adaptively compresses the depth buffer data according to different scene changes by employing 19 compression modes generated from three compression algorithms including DDPCM, HA, and general DDPCM. Furthermore, this novel algorithm supports one-plane and two-plane compression modes and manipulates...
