由Digital Tutors 公司出品的Digital Tutors Depth-Based Compositing in After Effects教程，After Effects深入基础合成教程

教程所使用的软件：After Effects CS4 and up

In this series of lessons we'll learn how to combine depth maps to create correct layering between two renders. This allows us to split out scenes into multiple render layers while keeping the correct pixels on top.

部分章节视频预览：

We'll begin by taking a look at what is depth-based compositing or layering and why we would want to use it. Then we'll learn about some of the downsides of using this technique. We'll then dive in to After Effects and create a matte for our foreground layer using it's depth map and the background depth map. We'll then learn how to work with depth maps including combining maps from different scene scales, using depth-based layering to fix interpenetration issues and making depth maps human readable and error-free.
