  • Cloth animation modeling
    Patent number: 6532014
    Abstract: A model for cloth, which allows for substantially real-time animation of the cloth, is disclosed. The latitudinal (vertical) nodes of the model are decoupled from the longitudinal (horizontal) nodes in one embodiment. In one embodiment, the latitudinal nodes are modeled as physical splines, and the longitudinal nodes are modeled as stiff multi-section rods between adjacent latitudinal nodes. The model is then rendered.
