Caustics ：焦散

焦散是一種很容易識別的間接照明效果。焦散的產生原理其實很簡單：間接照明光線(即光子)從光源發射出來後，先經過一次(或多次)Specular 表面反、折射作用，再投射到某個Diffuse表面上，最後以Diffuse的形式被攝影機 記錄 。此過程中的Specular表面被稱為 焦散投射物體 ，Diffuse表面稱為 焦散接收物體 。

教程簡介:

Caustics refers to the mathematical equations that describe how light converges in nature, such as the effect that is seen at the bottom of pools and lakes when light passes through the surface of the water. Cinema 4D can perform both surface and volume caustics. In this tutorial, you will learn how surface caustics can be used to create a pool with a floating translucent orb, and volume caustics can be applied to demonstrate a stained glass effect. Render settings, and time savers will also be discussed.
