Dive into the World of TouchDesigner GPU Particles and Optical Flow
This TouchDesigner showcase project was published by Derivative in 2023.
In this post, we’re going to be having fun playing with some GPU particles and optical flow in TouchDesigner, with a few easy tricks. Using only a few nodes in the network, I’ll show you how to create a particle system that responds to the motion of an incoming regular old RGB camera.
