Abstract
In this thesis, we propose a new caching technique, Radiance Volume, trying to integrate the advantages of current caching algorithms. Our goal is believable approximation of global illumination effects with high performance. Our framework can efficiently compute indirect illumination on both diffuse and glossy surfaces. By caching each record in the space instead of on the surfaces, we can efficiently handle light propagation and reflection around complex geometry. Moreover, we derive a radiance gradient computation method suitable for the caching scheme of Radiance Volume, which significantly improve the interpolation quality.
