System and process for digital generation, placement, animation and display of feathers and other surface-attached geometry for computer generated imagery

摘要

A system and process for digitally representing a plurality of surface-attached geometric objects on a model. The system and process comprises generating a plurality of particles and placing the plurality of particles on a surface of the model. A first plurality of curves are generated and placed at locations on the model. Characteristics are defined for the first plurality of curves. A second plurality of curves is interpolated from the first plurality of curves at locations of the particles. A plurality of surface-attached geometric objects is generated that replaces all of the particles and the second plurality of curves.
