Computer graphics researchers have made great strides towards
simulation of complex phenomena for special effects and other off-line
applications. A much less explored but equally important domain is
interactive virtual worlds including training simulations, computer
games, and other situations where interactivity is required. This
project explores the use of model reduction to achieve drastically
faster simulations of complex, high-dimensional phenomena. Our current
work focuses on incompressible fluids. Within this context we have
found that:
-
Speedups of up to 5 orders of magnitude are possible.
-
Kinetic energy can be preserved.
-
Moving objects can be correctly incorporated into the flow.
We plan to extend this work to a wider range of phenomena, and to
general pair-wise interactions between model-reduced phenomena.
