An interactive modeling technique for hair styles

Abstract The display of human image is important for improving the user interface. It is still difficult, however, to generate realistic human images even for the advanced computer graphics of today. One of the reasons is the difficulty in shaping the specification and rendering of human hair. The specification of the shape of the object to be handled in the computer is called (geometric) modeling. The modeling of hair has relied mainly on handwork, and is very time-consuming. Here, we propose an interactive modeling technique using a 3D digitizer and an interpolation method for the generation of large amounts of hair. These methods drastically reduce the work for hair style modeling.
