This paper describes a method of human short hair modeling and real time animation. A method is proposed to model the short hair. First, a hair style model is derived from a scalp model interactively. Then, the hair model is derived automatically from the hair style and scalp models. Texture mapping is applied to hair model for a better visual effect. For animation, a method is proposed based on an approximation of the accurate physically-based hair model, from which the 3D morphing key shapes are derived. Then, the intermediate shapes are computed by applying 3D morphing. We have implemented it and compared the results with real hair. The visual quality and frame rate are satisfactory for real time applications.
