摘要： A method of animating feather elements includes: specifying initial positions for a skin surface and for feather elements; specifying positions for the skin surface at an animated time; determining a feather-ordering sequence for placing the feather elements on the skin surface; determining positions for skirt elements that provide spatial extensions for the skin surface at the animated time; determining positions for feather-proxy elements that provide spatial extensions for the feather elements at the animated time; and determining positions for the feather elements at the animated time by extracting the feather elements from the feather-proxy elements. The feather-proxy elements are determined from the skirt elements according to the feather-ordering sequence, and the feather-proxy elements satisfy a separation criterion for avoiding intersections between the feather-proxy elements.
