Shadow acceleration in ray tracking using cache mechanisms.

摘要

This thesis presents methods for optimizing the shadowing process in ray traced scenes using cache mechanisms. The methods allow reduction of the computational burden of generating shadowed ray traced renderings. The methods include temporarily caching objects to allow for fast future reference. The thesis considers management of the shadowing process cache using schemes such as Least Recently Used (LRU) and First In, First Out (FIFO). Experiments that analyze the performance for the shadowing processes are also reported. Using caching mechanisms to optimize some other parts of ray tracing processes is also considered.
