三维服装仿真中的参数化人体建模技术

三维服装仿真中,通常需要以不同体态特征的人体来展示穿着效果,例如服装的立体感以及合体性等。考虑到这一实际应用,提出了一种参数化人体建模的新方法。特征参数的确定依据人体测量学理论,模板和结果模型都表示为空间多边形网格,底层几何处理基于计算机图形学轴变形技术,同时引入了径向变形权重曲线来增加调整的灵活性。该方法具有操作简单,输入直观以及建模速度快的优点,能够有效满足三维服装仿真环境对个性化人体模型的需求。

Study on parameterized mannequin modeling in 3-D garment simulation

In 3-D garment simulation, mannequins with different shapes are usually used to show wearing effect such as stereoscopic impression and fitness etc. Taken into consideration this practical application, a novel method for parameterized mannequin modeling was proposed. Feature parameters are determined according to anthropometry. Both template and result models are described in terms of polygonal meshes. Lowlevel geometry handling is based on axial deformation technique in computer graphics. Additionally, Radial deformation weight curves also have been introduced to improve the flexibility of modification. The remarkable advantages of this method are the simplicity of operating, the intuition of input and the quick speed of modeling. The method can be effectively applied to 3-D garment simulation environment in need of individual mannequins.
