要旨:
The ability to perform interactive walkthroughs of global
illumination solutions including glossy effects is a challenging
open problem. In this paper we overcome certain limitations of
previous approaches. We first introduce a novel, memory- and
compute-efficient representation of incoming illumination, in the
context of a hierarchical radiance clustering algorithm. We then
represent outgoing radiance with an adaptive hierarchical basis, in
a manner suitable for interactive display. Using appropriate
refinement and display strategies, we achieve walkthroughs of glossy
solutions at interactive rates for non-trivial scenes. In addition,
our implementation has been developed to be portable and easily
adaptable as an extension to existing, diffuse-only, hierarchical
radiosity systems. We present results of the implementation of
glossy global illumination in two independent global illumination
systems.
