Clustering is expected to be one of the most efficient and promising solutions for data transmission in Vehicular Ad hoc NETworks (VANET). The particular characteristics of VANET, including highly dynamic network topology, unstable transmission channel, and various service requirements, pose challenges and difficulties on clustering algorithm design. In this paper, a clustering algorithm based on...
Shadow mapping is an efficient algorithm for real-time shadow rendering. This algorithm is image based. When a shadow map with limited resolution maps in to a large virtual scene, it will suffer from the aliasing errors due to it's insufficient sample. In this paper we present a real-time shadow mapping algorithm. We render some sub shadow maps respectively instead of render only one shadow map and...
