摘要
引入B样条对头发及发型进行真实感建模与仿真.由悬臂梁模型生成初始数据点,经B样条曲线反算生成自然弯曲的关键头发;由周期性闭合B样条曲线反算生成头发簇的截面曲线;利用B样条的局部性质对关键头发和截面曲线进行形状调整;在关键头发和截面曲线的基础上运用蒙面算法生成头发簇.最后在头部模型上按区域生成头发簇并进行光照渲染完成整体发型设计与仿真.结果表明,该方法对头发的控制比较简单,可以获得各种发型.
Modelled and simulated the real hair and hair style using B-spline. The key hair curves in the case of natural bend was generated by inverse operation of B-spline curve with the initial points data generated by the cantilever beam model. The section curve was generated by inverse operation of cyclic closed B-spline curve. Then used the partial property of the B-spline to adjust the shape of the key hair and seciton curves. Based on the key hair and seciton curves, a hair cluster was generated by skinning. At last, generated diffrent hair clusters in different area of the head model and render with light to accomplish the whole hair sculpting and simulation. The result of simulation demonstrates the method is simple in the controlling of hair, and can create various hair style
