Fluid animation is a computer graphics technique for producing the motion of fluids such as water, smoke, and fire. It simulates and renders velocity fields and density by approximating the Navier–Stokes equations with grid-based (Eulerian) or particle-based (Lagrangian, SPH, etc.) methods, and is used in film visual effects, games, and interactive demos. This page collects video material that walks through a simple 2D implementation following Jos Stam's method.
