关键帧动画很棒，但是本教学重点要讲解的是HOUDINI的核心动力，程序化动画与表达式制作教学。我们将学习各种不同的表达式来控制动画。因此大家要重新回忆起高中时候的数学公式了，我们开始学习吧。

教师介绍:
Ari Danesh是一位有12年大学教学经验的视觉特效师与交互式设计师。他最近在UCLA Extension, Moorpark College, 还有CSUN，Ai Hollywood教授HOUDINI，他当前专注的是流程化建模与动画，粒子系统，动力学系统，还有植物仿真。Ari Danesh是SideFX的HOUDINI讲师。

Keyframe animation is great but this module focuses on one of Houdini’s core strengths - Procedural animation and expressions. We will be learning all sorts of expressions to drive your animations. So blow off the dust of your old high school math book at let us begin.
