Applications such as animation and scientific visualization demand high performance rendering of complex three dimensional scenes. To deliver the necessary rendering rates, highly parallel hardware architectures are required. The challenge is then to design algorithms and software which effectively use the hardware parallelism. This paper describes a rendering algorithm targeted to distributed memory MIMD architectures. For maximum performance, the algorithm exploits both object level and pixel level parallelism. The behavior of the algorithm is examined both analytically and experimentally. Its performance for large numbers of processors is found to be limited primarily by communication overheads. An experimental implementation for the Intel iPSC/860 shows increasing performance from 1 to 128 processors across a wide range of scene complexities. It is shown that minimal modifications to the algorithm will adapt it for use on shared memory architectures as well.

2Grey Man

By S. R. Crockett

This novel is set in Scotland in turbulent times, and we are immediately introduced to intrigue and family strife. At Launcelot Kennedy's aunt's husband's funeral, he and his father are first hidden, then hustled away secretly for fear of being spies. Werewolves, murder, secret trysts, vengeance and siege are the backdrop to this tale as Kennedy is set against Kennedy in this chilling feud. ( Lynne Thompson)
