本教学是HOUDINI培训系统的入门教学，培训对象是那些改用HOUDINI的用户或者是新学员，通过本教学你将能学些到这个神奇软件的基本知识。HOUDINI在2002年获得了3D动画革新技术奖。我们将学习到HOUDINI的数据流方式是如何成为3D世界通用的做法，减少你的想法与现实之间的差距。

This video is the entry gate of cmi's Houdini training system. Aimed at new users and migrators from other animation packages, this training will give you the fundamentals you need to get started with this magical application. Learn this incredible piece of software which has received a Technical Achievement Award in 2002 for its revolutionary approach to 3D Animation. Discover how Houdini's data flow has become the natural language of 3d, reducing the distance between your ideas and reality.

Its all about Flow
Houdini's structure is the one of networks carrying data. Your workflow is Houdini's data flow and the other way around. The way you assemble ideas is the way you work. Houdini wont read your mind but you can read his, it's easy. If you understand underlying logic, you will immediately feel that its interface is efficient. That is why we don't rush into modeling a t-rex but teach you Houdini's language. - Keywords: houdini training, sidefx

The Inside and The Outside
Houdini's operator-based approach means that you immediately have access to the core of Houdini through the interface, because its one and the same. Nothing is hidden and everything is in front of you. Don't play hide-and-seek with special features. Having access to Houdini's core doesn't mean it's technical or difficult. Quite the contrary.

Houdini's Interface
Houdini 's latest version has incredibly sped up the way you work, making it way more visual. Navigate the history of your operators with the speed of thought, and in your network of nodes through the view port, in a 4th dimension! Learn the elements of the workspace of the interface, and understand every element of the gui is in the proper place.

Non-Destructive Approach
Houdini allows you to go back anywhere in your history of operations to make any change. This has no equivalent in the industry for pure 3d apps. This becomes essential in production where you must faces quick decision changes. Imagine a world where you do not lose anything of what you do, where every bit of work you produce something will be able to be reused later on.

Proceduralism And Data Flow

If you can work on 1000 objects as easily as one object without having 1000 different nodes to connect together, there will have to be a paradigm shift. Understand Houdini's revolutionary way to deal with complex scenes, which helped create is reputation.

Understand Procedural Selections
A key to Houdini's non-destructive paradigm is the procedural selections which evolve with the non-destructive workflow. You might want to change the height of a bridge and keep extruding only all the faces under a certain altitude to create your post and at the same time and be able to change the number of posts, while being sure each one has the proper length to adapt to the ground. Learn how to create procedurally-defined groups of points or primitives.

Whiteboards
Whiteboards have been an essential parts of cmi's innovation, which is now becoming a standard. They are back to help you understand what can't be explained by just talking. Traditional slide shows are back to recapitulate your knowledge. They're now available as additional pdf files for you to print.
