In this paper, we present an efficient global
illumination technique, and then we discuss
the results of its extensive experimental validation.
The technique is a hybrid of clusterbased
hierarchical and progressive radiosity
techniques, which does not require storing
links between interacting surfaces and
clusters. We tested our technique by applying
a multistage validation procedure, which
we designed specifically for global illumination
solutions. First, we experimentally validate
the algorithm against analytically derived
and measured real-world data to check
how calculation speed is traded for lighting
simulation accuracy for various clustering
and meshing scenarios. Then we test the algorithm
performance and rendering quality
by directly comparing the virtual and realworld
images of a complex environment.
