Abstract

This paper provides an overview of the many different ways that light interacts with surfaces in the natural environment to provide useful information for visual perception. It begins with a discussion of how the concept of light has evolved over the course of human history. It then considers a wide variety of optical phenomena including Lambert's laws of illumination, the effects of microscopic surface structure on patterns of reflection, the bidirectional reflectance distribution function, the refraction of transmitted light, chromatic dispersion, thin film interference, sub-surface scattering, the Fresnel effects, indirect illumination from multiple reflections, caustics, and the structure of the light field. The primary goal of this discussion is to provide the necessary background information to help students and young researchers more easily understand the scientific literature on the perception of 3D shape and material properties from patterns of image shading.

关于光线和图像着色的物理学教程。
本文概述了自然环境中光线与物体表面相互作用的多种不同方式,从而为视觉感知提供有用的信息。本文首先讨论了光的概念在人类历史进程中的演变过程。然后讨论各种光学现象,包括朗伯照明定律、微观表面结构对反射模式的影响、双向反射分布函数、透射光的折射、色散、薄膜干涉、次表面散射、菲涅尔效应、多重反射产生的间接照明、苛求和光场结构。本讨论的主要目的是提供必要的背景信息,帮助学生和年轻研究人员更轻松地理解有关从图像阴影模式感知三维形状和材料属性的科学文献。
