通过集成经过验证的数学公式来更好的模拟自然，从而让粒子动画去到一个更高的级别。想象一下，天空中有数千只小鸟，或者是一支半兽人军队在行军，还或者是一支鱼群在逃避捕食者。本教学将教授大家如何使用这一群体制作系统创建群体动画模拟效果。

Take particle animation to a new level by integrating proven mathematical formulas to better simulate nature. Imagine thousands of birds in the air, an army of orcs marching on the ground or a school of fish fleeing from a predator. This training will teach the viewer the basic principles of a multi-agent system and how to create crowd simulations in Houdini.

This training focuses on a basic concept of flocking simulations: steering behaviors. The algorithms created by Craig Reynolds can be used to simulate the movements seen in flocks of birds or fish.

This step-by-step training video introduces how steering behaviors work and how one can create complex simulations just by combining simple behaviors. The viewer will learn the common behaviors like "separation" or "cohesion" and how they interact with the agent抯 mind.

As a bonus this tutorial comes with a powerful library of a multi-agent system which you can use to create flocking and crowd simulations.
