Gumroad - Reaction Diffusion:
The provided Blender file contains an implementation of a Geometry Nodes template for executing and rendering Reaction-Diffusion (RD) simulations starting from Blender version 4.3. The RD model can simulate the interaction of the reagents and their molecular diffusion to produce complex organic structures for use in animations and scientific visualizations.
In the setup, two primary simulation types are basic reaction_diffusion_sim and the Gray-Scott model (premium version), which have numerous presets for greater realism and preset multiple templates. The parameters for diffusion, reaction rates, and texture inputs can be modified by the user for customization.
Some great features of Gumroad - Reaction Diffusion:
2D and 3D renderings, real-time brush-enabled simulations, custom meshes, and modification of the simulations. In the premium version, additional features are provided, such as 3D simulation, presets for Gray-Scott, conditioning through images, and real-life input meshes with low resolution.
The method is based on a Laplacian approximation of the mesh topology using Blur Attributes. Result accuracy is highly dependent on mesh topology. The fidelity of the output is increased through high-resolution meshes and improved computational methods.
