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.

渐进式算法将专门为两个应用程序开发--转移。该算法使用几何和属性输入的分层描述，结合增量有限面积法、蒙特卡洛法和计算互反射的混合方法，并在独立的图形工作站上实现。由于它们是为了产生准确的辐射传输解决方案而开发的，因此这些算法将潜在地应用于其他涉及辐射传输的领域，如计算机视觉和遥感。渐进式精化算法，如本研究计划中开发的算法，将作为未来工程算法开发的范例，这些算法专门设计为提供连续的图形输出。
