Claim One:
1. An apparatus for generating mesh models of feathers, comprising: a processor and memory; a geometrical model analyzer that analyzes groups of barbs included in a geometrical curve model of the feather, wherein each group of barbs faces a predetermined direction that is different from those of its neighboring groups; a calculator that calculates a number of grids for each of the groups of barbs, wherein the number increases as an average curve length for the curve lengths included in each of the groups of barbs increases; and a mesh model generator that constructs a polygonal mesh model from the geometrical curve model based on the number of grids by performing tessellation on each curved surface representing a group of barbs to extract points on curved lines that represent barbs, so that motion of the group of barbs is efficiently represented by the group of barbs' corresponding polygonal mesh.
