Interactive Dynamics
Our goal is to use physical simulation as an interactive
medium for building and manipulating a wide range
of models. A key to achieving this goal is the ability
to create complex physical models dynamically by
snapping simple pieces together, integrating the process
of model creation into the ongoing simulation.
We present a mathematical and computational formulation
for constrained dynamics that makes this
possible, allowing encapsulated objects, constraints,
and forces to be combined dynamically and simulated
efficiently. The formulation handles arbitrary objects,
including nonrigid bodies. We describe an implementation
for interactive dynamics, and discuss applications
to mechanism construction, geometric modeling,
interactive optimization data fitting, and animation.
