about

This project was a research project for the #node17 visuals and wasn't really aimed for production. It quite strictly reproduces the credited paper, since it mainly served as a reference for evaluating other algorithms and implementation attempts. The only deviations are the additional vorticity confinement routines, eliminating the restriction to a square and evenly spaced base grid, and using Jacobi instead of Gauss-Seidel solver in order to benefit from SIMD instructions.

The repo demonstrates one way how to take advantage of c++'s native speed (SSE instructions) in vvvv without the need for two separate dlls and interop.

Nodes

all nodes come 2d and 3d versions

• StableFluid: Creates and holds a fluid simulation space
• Evaluate: Drives the fluid simulation, giving access to global parameters
• SetVelocity / SetDensity: Sets the velocities/densities of the entire fluid simulation space
• AddVelocity / AddDensity: Adds velocities/densities to the entire fluid simulation space
• AddRadialVelocity / AddRadialDensity: Adds velocities/densities around the given center to the fluid simulation space (think of it as an emitter)
• AddRadial: Adds velocities and densities around the given center to the fluid simulation space
• GetVelocity / GetDensity: Returns the velocities/densities of the enire fluid simulation space
• Split: Returns the velocities and densities of the enire fluid simulation space
