Houdini 是一个特效方面非常强大的软件。许多电影特效都是由它完成：《指环王》中“甘道夫”放的那些“魔法礼花”，还有“水马”冲垮“戒灵”的场面，后天中的龙卷风等等，a52的汽车广告，反正只要是涉及DD公司制作的好莱坞一线大片，几乎都会有Houdini参与和应用。

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。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。

Digital-Tutors Creating a Dynamic Wet Map Shader in Houdini

In this Houdini tutorial, you?ll learn to realistically show wetness in your object shaders. To realistically simulate fluids (water, blood, paint, oil, etc), often a wet map is required to change the shading of an object where the fluid comes into contact with an object. These need to animate, not only while the fluid is active, but also afterwards to simulate drying. The usual solution, generating a wet map, or fixed set of images for a texture map has several drawbacks: fixed resolution, color depths, and difficulties applying across objects or to subsequent shots in the film. This Houdini training introduces a new method for simulating wet objects, a shader-based method that first generates a 3D cloud of animated wet points, then by creating a shader that will use this data to shade the wet or drying parts of the character that were previously in contact with a fluid. This will be accomplished without any need to create or rerun the original fluid simulation.
