This video was made as a fun collaboration between CG Forge and Ian Frederick. Here, we explore how to use optical flow for driving velocity vectors along the surface of an object in an interesting, organic way. This is just the start to what you can do with this technique though. With optical flow, you can take your simulations to the next level by introducing unique and interesting velocity values that go beyond the typical noises and workflows you see every day.

    Is the optical flow technique easily replicable by artists new to VFX, or does it require a deep understanding of simulation dynamics? https://mapsdrivingdirections.io

      If you're new to Houdini, then I would first recommend developing some fundamental knowledge first. You can get started by going here: https://www.sidefx.com/learn/getting_started/
