How to Build Procedural Neural Paths with POPX - TouchDesigner Tutorial

We grow procedural neural paths through a 3D head in TouchDesigner using POPX. Points scattered inside the head are wired together with the POPX Shortest Path solver, smoothed, and swept into colored tubes. Animated ramps drive scale and color along each path, so the network grows in, tapers, and dissolves over time. Inspired by Konstantin Magnus's Houdini shortest-path work:    / @konstantinmagnus   Project file: https://www.patreon.com/posts/procedu...
