Free TouchDesigner 2022.32660 Component: chainGpu GPU Chain Physics for Plants & Hair (Mickey van Olst)

Overview

Mickey van Olst shares chainGpu, a TouchDesigner component that simulates chain-like physics on the GPU with a compute shader, suited to flowers, plants, grass, tentacles, hair and trees. Each segment has a target orientation from which a linear velocity is calculated, which gives organic motion that works with gravity, wind, turbulence and colliders.

The included demo toe has four annotated examples: a basic setup, recursive flowers anchored to a stem, chains spawned on a teapot that deform a Tube SOP, and a chain initialized from a path SOP. It was tested on TouchDesigner 2022.32660 for Windows, is marked for non-commercial use only and is a free direct download from GitHub.
