AE原子细胞模拟 AETUTS Atom Simulation in After Effects:Part 1-2一共两部分教程，在AE中通过Particular和 CC Sphere来模拟制作原子细胞效果，为了使场景看起来是在3D中完成的，我们会在AE中运用一些表达式和技巧来让2D图层展现出3D效果。

包含工程文件。

In this tutorial we’ll create an atom simulation using Particular, CC Sphere, a few layers along with some tricks and smoke screens.

In order to make this scene a true (AE) 3D scene we will use some expressions and AE tricks to make the 2D layers act as 3D layers, and respond to the camera.

This scene is quite simple and straightforward, but it is compiled out of lots of small steps.

We got a lot to do, so let’s get started.
