Summary:Animating the drape of different cloths must address complex
physical behaviors. This particle approach uses optimizations that make
it faster than earlier implementations and allow it to simulate behavior
over time. The modeling system presented computes the full trajectories
of particles and not just the final positions. This offers several
important advantages. Since the full history of each particle is known,
hysteresis effects can be modeled accurately. The Kawabata (1980)
experimental data for different textiles can be input directly to the
model. The effects of external forces, especially those produced by wind
or moving solid bodies, can be modeled accurately. Despite this extra
dimension of detail, our system computes final positions considerably
faster than the times given by Breen, House and Wozny (1994). Our model
can be easily extended to simulate the effects of manufacturing
processes or interacting bodies. In particular, high stresses of the
kind that occur in manufacturing can only be modeled if the full
trajectory of each particle is known. We have implemented our model as a
C++ class library. Particle systems are more flexible than approaches
using continuum mechanics. Our system's fast computation times, mainly
due to the numerical solution of ordinary differential equations,
compare favorably to approaches using a finite-element method.
Therefore, our approach might be an interesting alternative for other
engineering problems currently solved by a finite-element method, for
example, the computation of minimal surfaces, heavy membranes, vibrating
membranes and population dynamics
