面向毛绒玩具的三维毛发造型方法

3D fur modeling method of plush toy

模拟真实毛绒玩具表面的毛发形态并直观展示出来对于设计人员设计出逼真的毛绒玩具起着十分重要的作用。针对毛绒玩具毛发的特点,提出了面向毛绒玩具的三维毛发造型方法。首先,基于一种动态参数化的三维彩绘技术,采用草图绘制的方式在三维模型表面绘制纹理图案,确定毛发的生成区域及颜色信息;然后,基于一种引导线的毛发模型对单根毛发进行建模;最后,针对毛发集合的属性,采用多种交互的控制方法实现不同的毛发形状效果。实验总结出四种常用毛绒玩具的毛发模型参数,且系统的学习速度和造型速度分别是Blender的27.87倍和27.78倍;实验结果证明,该方法可以方便快速地在三维毛绒玩具模型表面生成各种毛发造型,为毛绒玩具设计师提供了简单易学的毛发造型工具。

Simulating the fur of plush toy and displaying them directly is very important for designers to design realistic plush toys.According to the fur characteristics of the plush toy,a three-demensional(3D)fur modeling method was proposed.Firstly,a 3D painting technique was employed to design textures of a 3D model using sketch based drawing,which was used to specify the regions and color properties of the fur.Then,a guide line based fur model was established to model a single fur.Lastly,based on the properties of the fur collection,the shape of the fur was controlled using several interactive approaches.Fur parameters of four commonly-used plush toys were summarized,and the learning speed and modeling speed of the proposed system is 27.87 times and 27.78 times that of Blender respectively.Experimental results show that various 3D fur shapes can be designed efficiently and conveniently using the proposed method,which provides an easy-to-use and easy-to-learn 3D fur modeling tool for plush toy designers.
