Abstract

Hair models of human or, animal hairs are displayed on a display screen using a three-dimensional computer graphics technique. Each human hair model is constructed of a plurality of rod-shaped hair elements. The magnitude and direction of an external force applied to each hair element are designated. A deformation quantity of each hair element is obtained such that the external force having the designated magnitude and direction equilibrates with an internal force generated by the rigidity of each hair element. The shape of each hair model is determined in accordance with obtained deformation quantities, for display of the shape of each hair model. The hair model can be displayed man-machine interactively.
