| dc.description.abstract | This dissertation presents a robust method of modeling objects and forces for computer animation. Within
this method objects and forces are represented as particles. As in most modeling systems, the movement of
objects is driven by physically based forces. The usage of particles, however, allows more artistically
motivated behavior to be achieved and also allows the modeling of heterogeneous objects and objects in
different state phases: solid, liquid or gas. By using invisible particles to propagate forces through the
modeling environment complex behavior is achieved through the interaction of relatively simple
components. In sum, 'macroscopic' behavior emerges from 'microscopic' modeling.
We present a newly developed modeling framework expanding on related work. This framework allows
objects and forces to be modeled using particle representations and provides the details on how objects are
created, how they interact, and how they may be displayed. We present examples to demonstrate the
viability and robustness of the developed method of modeling. They illustrate the breaking and fracturing
of solids, the interaction of objects in different phase states, and the achievement of a reasonable balance
between artistic and physically based behaviors. | en |
