How to create a laser scan the follows a surface
on Dec 1, 2017 at 10:43:58 pm

I'm trying to create a laser scan that follows a surface similar to those shown in these videos:

I can currently create a terrain using Trapcode Form with a displacement map and then throw another Form layer on top that "follows" the terrain. But how do I create a laser beam that follows other surfaces?

As I see it, you need a z-depth map for everything that you need the laser to trace the surface of. For anything that isn't created in 3D, you need to do either a manual depth map or some resemblance of it. For moving objects (such as people), I'd try something like a blurred cutout of the person, masked with a duplicate sharp track matte of the same.

Thanks. I'll give that a try.
