要旨:
Realistic image synthesis requires both complex and realistic models
of real-world light sources and efficient rendering algorithms to deal
with them. In this paper, we describe a processing pipeline for
dealing with complex light sources from acquisition to global
illumination rendering. We carefully design optical filters to
guarantee high precision measurements of real-world light sources. We
discuss two practically feasible setups that allow us to measure light
sources with different characteristics.
Finally, we introduce an efficient importance sampling
algorithm for our representation that can be used, for example, in
conjunction with Photon Maps.
