Abstract
The computational requirements of full global illumination
rendering are such that it is still not possible to achieve
high-fidelity graphics of very complex scenes in a reasonable time
on a single computer. By identifying which computations are more
relevant to the desired quality of the solution, selective
rendering can significantly reduce rendering times. In this paper
we present a novel component-based selective rendering system in
which the quality of every image, and indeed every pixel, can be
controlled by means of a component regular expression (crex).
The crex provides a flexible mechanism for controlling which
components are rendered and in which order. It can be used as a
strategy for directing the light transport within a scene and also
in a progressive rendering framework. Furthermore, the crex can
be combined with visual perception techniques to reduce rendering
computation times without compromising the perceived visual
quality. By means of a psychophysical experiment we demonstrate
how the crex can be successfully used in such a perceptual
rendering framework. In addition, we show how the crex's
flexibility enables it to be incorporated in a predictive
framework for time-constrained rendering.
