【摘要】 针对人体模型在服装行业的应用,提出了一种基于曲面建模与多边形建模的混合人体建模方法.该方法根据人体不同部位对于模型动态改变中的不同作用分为动态部位和静态部位.动态部位是指在系统中需要根据个体特征尺寸进行调整的部位;静态部位是指变动可以忽略的部位.动态部位采用基于切片的NURBS参数化曲面建模方法,可以满足这些部位根据个人特征尺寸进行调整;对于静态部位,采用多边形建模方法,能更快捷、方便地予以定性描述.实验证明该方法能高效地、快捷地实现人体模型的实时生成和实时调节.更多还原

【Abstract】 In this paper,a virtual human modeling method based on curved-surface modeling and polygon modeling is presented for garment industry.According to the different effects on the human model’s changing,the human body is divided into two parts: dynamic part and static part.Dynamic part refers to the part which should be adjusted according to the personal characteristic measurements.Static part refers to the part whose change can be ignored when the human model changes.Curved-surface modeling based on slice is adopted for the dynamic part’s modeling,which can satisfy the adjustment based on characteristic measurements.Polygon modeling is then employed for the static part’s modeling to achieve a certain visual effect.It is proved through examination that this method is efficient for the virtual human’s modeling and real-time adjusting.更多还原
