摘要: 针对现有头发模型缺乏柔性的问题,提出一种改进的基于超螺旋模型的头发建模与仿真方法,将导引发丝构造成具有有限自由度的分段螺旋体,运用拉格朗日力学对发丝运动进行计算。通过改进卷发曲率和捻度的计算方法,并采用自适应控制结构对头发进行重组和细分,提高模拟过程的准确性和稳定性。实验结果证明,该方法可以获得较为逼真的动态模拟头发的效果。

Abstract: Aiming at the lack of flexibility of the existing hair model, a method for hair modeling and animation based on super-helix model is improved. This approach guides hair strands to cret helical segments with a finite number of degrees of freedom, and it uses Lagrangian mechanics for its equations of motion. By improving the method for calculating the curvature and twist of curly hair, the paer adopts a control structure named Adaptive Wisp Tree(AWT) for adaptive clustering and subdivision to increase the accuracy and stability during the process. Experimental result demonstrates the method can create realistic motion of hair.

Key words: hair modeling, super-helix model, curvature of curly hair, twist, Adaptive Wisp Tree(AWT)
