This looks like a very neat addition to After Effects. Looking at the previews (I haven’t bought it), I’m fairly certain it’s done without any external plugins, but utilizing build-in effects with expressions.
- Create a bunch of 3D layers using the image as the texture, offsetting them in Z-space and scaling them up to appear the same size from the camera. See this script for an example
- Use the depth map as a mask, offsetting the value on each layer.
