本教程是由cmiVFX机构出品的Houdini流程化动画制作技巧教程，时长：2小时57分，教程使用软件：Houdini，大小：705.61 MB，MP4视频格式，作者：Andreu Lucio lucio，语言：英语。

本教学能够帮助动画师使用HOUDINI中大量不同的技巧与方法来创建特效，虽然HOUDINI的学习是个艰苦卓绝的过程，但是基本上没有什么是HOUDINI不能做的。本教学将教授大家一些基本的概念，并且教授大家一些非常强大的动画工具。

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

cmiVFX Houdini Procedural Animation Techniques

cmiVFX launches its latest Full Feature training video using The Foundry’s Nuke line of digital compositing products. In this in-depth Nuke training video, you will learn, step-by-step, everything you need to create perfect mattes from green/blue screen footage! Learn multiple ways to approach the keying process to prepare you for any shot, and the inevitable challenges that arise. You will learn proven ways to fix trouble areas like hair, and to deal with color spill from the green or blue screen. Color spill is almost always always a problem and eliminating it is one of the most important aspects of selling a shot. After learning the techniques outlined in detail here, Nuke will become your keying and channel operations playground!

Houdini Procedural Animation Techniques

This video was created to assist animators, teaching a series of different techniques and methods for building effects inside Houdini. Houdini, while being incredibly deep with a formidable learning curve, also happens to be one of the most (if not the most) versatile and powerful non-proprietary graphics package available. There is virtually nothing Houdini can't do, but this video will help teach fundamental concepts and provide focus and direction to a number of the incredibly powerful animation tools. cmiVFX breaks down each step one by one with fast and easy chapter references designed for even faster muscle memory. cmiVFX continues to deliver the training and content you need, quickly, efficient and affordably.

Controlled Animation of Multiple Objects

As you may already know, it is crucial to be able to control every aspect of a given shot; making changes quickly and easily to an entire scene with the ability to immediately see the effect of those changes results in an environment geared perfectly for art direction and decision making. With these techniques, we can animate a single object using dynamic VOPs, CHOPs, and keyframes rr-sc.com and then procedurally duplicate the entire network, resulting in the ability to parametrically control an infinite number of objects. CHOPs allow us to import an already keyframed parameter, apply that animation to each object, and then modify each object's animation channels independently. This allows for gigantic animations controlled by only a few nodes. We'll also use VOP networks to control when and where the animations take place.

Procedural Lightning Effect

Here you will learn to easily create a complex-looking lightning effect. The trick is to combine nurds modeling with CHOPs and the "ForEach" node to get a completely procedural and controllable lightning rig that allows for an infinite number of lightning bolts. The goal here is to learn the importance of choosing the right method for achieving a given result, with the least complex networks possible.

Rigging a Procedural Tentacle

Using bones and CHOPs together, we will learn how to quickly rig, animate, and instance a tentacle procedurally, as well as modifying the animation for each copy without having to duplicate any networks. Traditional animation would take forever to achieve such a slick result. Combining more channels just increases the complexity of the look.

The Power of Recursive Animation

The SOP Solver gives us the opportunity to create recursive animations and modeling, where each frame, the geometry of the previous frame is passed forward and the whole network inside the solver is recalculated. This allows for effects using propagation, in this case, a growing area of points in a different group. We can then use this changing group data to animate things burning, melting, or simply changing in some way. Learn to calculate the distance from a given point and have each selected point add to its group based on the neighboring points, and then have the calculations repeat each frame to grow the group. This will be accomplished using the VOPSOP and the SOP Solver.

Creating Fully Dynamic Jellyfish Heads

Learn to create local forces for wire or cloth objects and combine them with keyframed geometry deformations to create dynamic soft-body objects mixed with sinusoidal animation. This technique will allow for incredibly versatile and interesting self-propelled soft bodies or cloth.

About The Author

Andreu Lucio is a spanish cg professional with more than 10 years experience and is 32 years old. After studying visual communication, he started working in international cartoon series in 1999, "The triplets", "Juanito Jones" and "Tom" as a Cg Artist for a company called Cromosoma. He become the Lead Cg Artist so learned a lot about light, colors, compositing, fx and how important they are for improving the final result. During his carrier working in some of the top spanish studios he has deeply use softwares like 3d Max, Maya, Houdini, Modo, Combustion, Nuke. Stuff like dynamics, expressions, maya mel and python had been present almost always in his long r&d sessions. Never stopped learning neither working so how to fit developed techniques in the real production its been the key goal for him. For the last 3 years he is working in Torsion Animation, a small Houdini based studio that has co-founded, creating motion graphics and visual fx for commercials. The studio is really small, so it has to use his skills from modeling to compositing and Houdini′s power in order to get the job finished within the tight deadlines and the high quality demanded.
