Abstract
A realistic feather growth may be represented between two surface manifolds in a modeling system. To perform the feather growth, a feather groom for a plurality of feathers between an inner shell of a creature and an outer shell of the creature is received. An inner manifold for the inner shell and an outer manifold for the outer shell is determined with a plurality of follicle points and a plurality of tip points. A first surface contour definition for the inner manifold and a second surface contour definition for the outer manifold is determined and used to determine a volumetric vector field between the inner manifold and the outer manifold. Thereafter, the plurality of feathers is generated between the inner manifold and the outer manifold using the follicle points, the tip points, and the volumetric vector fields.
