Provided are an apparatus and a method for generating mesh models of feathers. The apparatus for generating the mesh models of the feathers includes a geometrical model analyzing unit that analyzes groups of barbs included in a geometrical curve model of the feather; a calculating unit that calculates the number of grids for each of the groups of barbs by applying curve lengths of the barbs and an average length of the curve lengths included in each of the groups of barbs; and a mesh model generating unit that constructs the geometrical curve models as polygonal mesh models based on the number of grids. According to the present invention, it extracts curved points by using characteristics of a model of a feather and constructs polygonal meshes by using the extracted curved points, thereby making it possible to physically and realistically express the forced physical variation of the polygonal meshes.
