Global illumination algorithms provide a way to model the different light transport phenomena seen in real life, and produce accurate images. The amount of computation to achieve accurate rendering is large, resulting in the development of many different ways of speeding it up. Some of these focus on speeding up the basic processes of rendering, such as ray tracing operations, and some on leveraging parallel hardware to speed up rendering. Two novel algorithms of this type are described in this thesis. One to allow incoherent paths to be efficiently be traced in parallel by offsetting the latency. The other discovers and exploits empty regions of space to avoid the use of acceleration structures for such operations as soft shadowing and metropolis light transport mutations. The other approach to speeding up rendering is to use a more elegant algorithm. Two such families of algorithms are photon mapping and metropolis light transport. Extensions to progressive photon mapping and hybrid algorithms using photon mapping and metropolis light transport are presented., showing significant speedup in complex scenes that present difficulties to current rendering algorithms.
