摘要

In this paper, we implement an interactive relighting system based on mesh-dependent basis for allfrequency geometry relighting, supporting multiplebounces indirect lighting effects in scenes with diffuse materials under dynamic global and local lighting. This generalized mesh-dependent basis is generated by using a statistical approach, eigenanalysis, as we can derive it from principal component analysis of either direct transfer matrix (DTM) or total transfer matrix (TTM), and the latter performs better. Furthermore, our system is easy to implement and can be easily integrated into content generation pipelines used in computer games for the purpose of getting more richness visual effects, especially inter-reflections in our case,
