FLIP Fluid

A FLIP/PIC liquid: a block of water is dropped and left to churn and settle. Each step scatters the particles' velocities onto a grid, makes that grid divergence-free with a Jacobi pressure solve (the incompressibility that gives water its body), then gathers the corrected velocity back — blending PIC stability with FLIP's lively splashes. Thousands of particles drawn as soft metaball discs.
