提出了一个真实感短毛的实时绘制与造型系统。该系统采用快速的层状纹理切片技术进行毛发表示，保证了真实感短毛绘制和造型的实时性。在毛发造型方面，系统采用倒伏向量场和长度标量场来控制模型表面短毛的形态变化，并提供了多种造型工具，如梳理、吹风、引力棒、插值、扰动等。利用这些造型工具，用户可以灵活、直观地对短毛形态进行编辑与设计。系统还提供了一个毛发纹理生成器，使用户可以通过设计毛发纹理来对毛发的粗细、疏密和颜色等属性进行整体控制。实验结果表明，本文系统具有较强的短毛造型能力，并具有非常好的可操作性和用户交互性。

This paper presents a system for real time modeling and rendering short fur. In the system, multi layer textured slices are employed to represent furry surfaces, and the high rendering performance is achieved. The system utilizes a vector field as well as a scalar field to control the shape variations of furry surfaces, and provides several fur modeling tools, including the comb, the blower, the attractive stick, and the tools for interpolating, smoothing and disturbing fur, by which users can model fur shape conveniently. In addition, a fur texture creator is provided for designing various fur textures that can affect the final rendering results of furry surfaces. The experimental results show that the system has good modeling capability and is easy to use.
