Free TouchDesigner GLSL Navier-Stokes Fluid Simulation Project (Noah Norman)

Overview

Noah Norman (ancillarymagnet) shares a Navier-Stokes fluid simulation built in TouchDesigner with GLSL, crediting Jos Stam, GPU Gems and PixelFlow as sources. NN_fluids.toe lets you paint ink and force with the mouse in the parent viewer, change resolution and dissipation through custom parameters, and feed your own force, ink and obstacle textures into labelled nulls.

The README explains the pixel formats, such as force stored as floating point in the red and green channels, and notes that ink can have negative values to subtract color. The project and its GLSL files are a free direct download from GitHub under the MIT license.
