The realistic appearance of objects is strongly influenced by how light behaves with (i.e. on and under) its surface. Light transport depends of various physical properties of the surface. In computer graphics, they are mostly modeled by geometrical optics, such as the distribution of its meso- and micro-structures, each structure having its own physical properties. This hierarchy of scales for a surface is a fundamental concept; it distinguishes an object from its surface. However when observed from different distances and view angles, this appearance can have a highly non-linear visual behavior.

物体的真实外观很大程度上受到光在其表面（即表面上和表面下）的影响。光传输取决于表面的各种物理特性。在计算机图形学中，它们大多通过几何光学来建模，例如其细观和微观结构的分布，每种结构都有自己的物理特性。表面的这种层次结构是一个基本概念。它将物体与其表面区分开来。然而，当从不同的距离和视角观察时，这种外观可能具有高度非线性的视觉行为。
