要旨:
We investigate applications of the Visible
Difference Predictor (VDP) to steer global illumination
computation.
We use the VDP to monitor the progression of computation as a function
of time for major global illumination algorithms.
Based on the results obtained,
we propose a novel global illumination algorithm
which is a hybrid of stochastic (density estimation) and
deterministic (adaptive mesh refinement) techniques
used in an optimized sequence to reduce the
differences between the intermediate and final images as
predicted by the VDP.
Also, the VDP is applied to decide upon
stopping conditions for global illumination
simulation, when further continuation of computation does not
contribute to perceivable changes in the quality of the resulting images.
