Houdini粒子模拟特效教程 CG Circuit – Advanced Particles 1 Geometry Based Simulations讲解Houdini中粒子特效模拟，利用多边形来模拟不同参数效果的粒子以及对粒子的控制等In this course we will take an alembic animation of an opening hand, and use it to generate particles.

We will learn how to use the geometry to create different attributes and how to get our particles to use those attributes.
