This software tutorial shows you how to use Trapcode 3D Stroke plug-in for After Effects. 3D Stroke uses paths from one or more masks to render volumetric strokes that can be rotated and moved freely in 3D space. It even has a built-in camera to create dynamic 3D environments. Path reveals are easy to make with keyframeable start and end sliders. If you've never used 3D Stroke, get started with this After Effects tutorial.
