Abstract:
A physically based model of an object is a mathematical
representation of its behavior, which incorporates principles
of Newtonian physics. Dynamic soil models are required in
animations and realtime interactive simulations in which
changes of natural terrain are involved. Analytic methods,
based on soil properties and Newtonian physics, are presented
in the paper to model soil slippage and soil manipulations.
These methods can be used to calculate the evolution of a given
soil configuration under the constraint of volume conservation
and to simulate excavating activities such as digging, cutting,
piling, carrying or dumping soil. Numerical algorithms with
linear time and space complexities are also developed to meet
the requirement of realtime computer simulation.
