摘要

This dissertation is about the parallelization of an algorithm that has becomeknown as the two-pass radiosity method, for rendering artificial scenes with photo realism on the screen of a workstation. It first provides the background for the radiosity method and ray tracing. It then presents a ray-tracing based two-pass approach that serves as basis for the target algorithm. It then presents the shelling technique. By and large, it is an algorithm that strives to build the visibility orderings for the sets of input patches and rays. It then turns to the resource management problem. It first points out some dynamic behaviors like latencies in memory accesses, communications and synchronizations which make the scheduling problem very difficult to manage and analyze at compile time. This leads to a so-called runtime resource management problem which defers the actual scheduling to some point during program execution. Next, it presents the system configuration of the radiosity engine, and discusses some essential issues such as the memory structure, network design and synchronization mechanism and gives an outline of the functionality of the system. Finally, it quantifies the performance of the radiosity engine by using Monte Carlo simulation, and gives some conclusions.
