ABSTRACT
Smoothed particle hydrodynamics (SPH) [Monaghan 88] is a method for simulating nonrigid substances in real time as clouds of particles, with applications ranging from water to soft bodies and gaseous phenomena. Contrary to fluid simulations based on a fixed Eulerian grid, as treated in [Harlow and Welch 65] and [Stam 99], the particle cloud is free to move anywhere in space and dynamically change the resolution of any area of the simulation to suit its importance to the observer.
