3D Reaction Diffusion in TouchDesigner using POP–TOP Feedback
In this tutorial, we build an experimental 3D reaction-diffusion–style system in TouchDesigner using feedback between POPs and TOPs. Particle data is converted into image space, processed image-based effects, then fed back into POPs o create evolving, emergent structures.
The focus is on iterative feedback, real-time control, and improvisation, with the right settings these simple operations can produce complex 3D forms.
The project file (including GLSL component) is available on Patreon Patcher Tier: https://www.patreon.com/posts/3d-reaction-in-145680911
A selection of different presets and visualisation methods will be available from 13/12/25 on Patreon Component Tier. A selection of some different presets and looks can be seen from 24.05 onward.
