Title: A Particle-based model for water simulation

Conference ·
OSTI ID:310908

The Smooth-Particle Applied Mechanics (SPAM) model is a relatively recent physical modeling technique It can model both fluids and solids using free-moving particles An implemented SPAM model is described that solved the compressible Navier-Stokes equations to produce animations of splashing and pooling water Because the particle positions are known explicitly each timestep, the SPAM technique produces data amenable to visualization A ray-tracing renderer is also described It samples the underwater light-field distribution and stores tbe information into a Light Accumulation Lattice which is used for scattered light calculations and caustics.
