Physics-Based Lighting Models: Implementation Issues

This paper provides tools to implement a physics-based lighting model. This latter uses a physics-based reflection model, spectral distribution of light powers and does not make any assumption on the specular behaviour of materials. The scenes are discretized into points instead of patches. A data structure named visibility graph is built to efficiently evaluate the visibility between two sample points. This global model is implemented according to a two-pass method.
