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 […]
