Progressive Refinement Algorithms for Radiant Transfer

点击翻译按钮获取中文摘要

The progressive algorithms will be developed specifically for two applications -- the transfer. The algorithms are developed using hierarchical descriptions of the geometric and property input combined with incremental finite area, Monte Carlo, and hybrid methods for calculating interreflections and implemented on a stand alone graphics workstation. Because they are developed to produce accurate radiant transfer solutions, the algorithms will potentially be applicable in other fields involving radiant transfer as computer vision and remote sensing. Progressive refinement algorithms such as those developed in this research program will serve as examples for the development of future engineering algorithms which are specifically designed to provide continuous graphical output.
