Physics-based modeling and simulation
(Fedkiw)
• new computational algorithms for numerical
simulation of physical phenomena
Water - simulated using the Navier Stokes equations and the level set method
for implicit surface evolution. A solid “invisible” sphere initiates the splashing.

Physics-based modeling and simulation
(Fedkiw)
• new computational algorithms for numerical
simulation of physical phenomena
Smoke - simulated as a scalar in a flow field generated using the
Navier Stokes equations. Photon mapping is used for the visualization.
