Abstract:

Computer animation has emerged as an important area of computer
science, generating billions of dollars in the film and video game
industries and captivating audiences around the world.  Physical
simulation is an important tool for computer animation because of its
ability to generate extremely realistic behaviors of complicated, high
degree-of-freedom systems. Simulation of liquids, explosions, and
fracture have been used extensively for generating special effects.
In this talk, I will present a semi-Lagrangian contouring method for
tracking liquid surfaces in fluid simulations.  Our method takes the
unusual approach of representing the liquid surface explicitly with a
polygonal mesh.  However, our approach updates the surface in time
through an implicit representation, thereby avoiding topological
issues. We then extract a new polygonal mesh from this implicit
representation.  Our technique generates nice looking, very detailed,
and temporally coherent surfaces suitable for high-quality computer
animation.  I will also briefly discuss our methods for simulating
the behavior of viscoelastic liquids and elastoplastic solids, such
as clay, gels, and mucus.
