Quantized Reaction Diffusion in TouchDesigner & T3D

This tutorial uses TouchDesigner and T3D to create “quantized reaction diffusion.” This is my concise way of saying: a bounding volume of quantized noise, which guides the growth of 3D reaction diffusion into boxlike structures.

T3D is a collection of operators in TouchDesigner that allows you to work with 3D Textures. T3D 1.8 can be found on Josef Pelz’ Patreon. https://www.patreon.com/JosefPelz/

The project file for this tutorial is available on my Patreon https://www.patreon.com/Polyhop There you gain access to additional project files, help guide future topics and support the creation of new tutorials. Note that the project file contains only the T3D components necessary for the tutorial but the tool has been removed

In this video I’m using TouchDesigner Version 2023.12120. If you’re using an older or newer version there may be features that don’t work in exactly the same way.
