One important visual cue of objects in the real world has to do with how they become more reflective at grazing angles (illustrated below). This is called the Fresnel effect.
现实世界中物体的一个重要视觉线索与它们如何在掠射角度变得更具反射性有关(如下图所示)。这叫做菲涅耳效应。

The fresnel effect visible at grazing angles in relation to the viewer is increasingly apparent as the surface of a material becomes smoother
当材质表面变得更加光滑时，相对于观察者而言，在掠射角可见的菲涅耳效应变得越来越明显

There are two things to note in this example; firstly, these reflectio
