Abstract:
Every time a tabelcloth is draped over a table it will fold and pleat
in unique ways. We report on a physically-based model and a simulation
methodology, which when used together are able to reproduce many of the
attributes of this characteristic behavior of cloth. Our model utilizes
a microscopic particle representation that directly treats the mechanical
constraints between threads in woven material rather than using a
macroscopic continuum approximation. The simulation technique is hybrid,
employing force methods for gross movements and energy methods to enforce
constraints within the material. The model is developed and demonstrated
within a visualization environment that allows full interaction between
the simulated material and conventional constructive-solid-geometry
models.
