Abstract

We introduce a ray based technique to approximate global illumination for complex scenes. If perfect accuracy is not needed, our approach is a simple but more efficient alternative to prior ray based approaches like ray mapping. Our approach combines the simplicity and efficiency of photon mapping with the bias reduction of ray based techniques. The tradeoff between accuracy and efficiency is controlled by only a single parameter. Moreover our algorithm can be easily integrated into existing photon mapping based frameworks.

Keywords: global illumination, hair modelling, hair rendering
