Abstract

The study of the physical process of light interacting with matter is an important part of computer image synthesis since it forms the basis for calculations of intensities in the picture. The simpler models used in the past are being augmented by more complex models gleaned from the physics literature. This paper is another step in the direction of assimilating such knowledge. It concerns the statistical simulation of light passing through and being reflected by clouds of similar small particles. (It does not, however, address the cloud structure modeling problem). By extension it can be applied to surfaces completely covered by dust and is therefore a physical basis for various theories of diffuse reflection.
光反射功能,模拟云和尘埃表面
光与物质相互作用的物理过程的研究是计算机图像合成的重要组成部分,因为它构成了计算图像强度的基础。过去使用的简单模型正被从物理文献中收集的更复杂的模型所增强。本文是朝着吸收这些知识的方向迈出的又一步。它涉及光通过由类似小粒子组成的云并被云反射的统计模拟。(然而,它没有解决云结构建模问题)。通过扩展,它可以应用于完全被灰尘覆盖的表面,因此是各种漫反射理论的物理基础。
