Modeling Curly Hair Based on Static Super-Helices

In the field of computer graphics and human simulation, hair simulation is one of the most challenging physics and rendering problem. This paper presents a curly hair modeling utilizing the Nelder-Mead method and being based on the ball B-Spline Curves (BBSCs). The ball B-Spline Curves (BBSCs) is used to reconstruct hair model and the Nelder-Mead method is for calculating the equilibrium shape of each hair. The main advantages of our method used in this experiment are: (1) We construct hair model for each individual hair. (2) It can provide a wide range of curly hair types with the BBSCs for its good properties that it is flexible for modifying, editing and deforming. (3) The method can obtain efficient curly hair type because of the fast calculation and easy implementation of Nelder-Mead method. The hypothesis in this paper is supported by several credible evidences and the model can be widely used in the similar systems (e.g. Fabrics, green fields).
