Houdini不光只适用于视觉特效的制作，随着HOUDINI适用于各种平台，并且出现了很多的HOUDINI培训教学，HOUDINI开始进入了动态图像设计领域人人素材。因为其自身的流程化特性，加上其强大的动力学系统，让HOUDINI在数据可视化方面占有一席重要的地位，让图形设计师能够通过它表达自己的观点。
cmiVFX Houdini Caustics
Setting Up
Knowing how to setup the scene is a very critical step to get good refractions and reflections, then after that caustics, so first you will learn how and why to setup the scene the way it is, and how to define the interior and exterior of your surfaces.
Materials
Understanding the creation of refractive materials for the water and the glass objects are the soul of a proper caustic effect, so you`ll learn it and assign them to their corresponding objects.
Photons
In real life they are the main actor behind all the lights we see and interact with. To be able to create caustics first of all, photons have to be shot into the scene. here you will learn how to shoot the photons into the scene and how to visualize them.
Optimizations
Now that the photons are in the scene, in this part other textures and materials will be assigned, then those photons will be used to create caustics either by using the Micropolygon, raytracing or the PBR engine. then optimization and improvements techniques will be discussed.
