摘要

从电磁学的问题出发，提出了一套新的照明模型。这些模型描述了光从具有各向异性的表面(具有首选方向的表面)反射和折射。该模型允许一种新的映射技术，我们称之为帧映射。我们还讨论了几何模型之间的一般关系，所有类型的表面映射，以及在极端复杂的渲染图像的背景下照明模型。

Anisotropic reflection models

We present a new set of lighting models derived from the questions of electromagnetism. These models describe the reflection and refraction of light from surfaces which exhibit anisotropy---surfaces with preferred directions. The model allows a new mapping technique, which we call frame mapping. We also discuss the general relationship between geometric models, surface mapping of all types, and lighting models in the context of rendering images with extreme complexity.
