1、基于通用软件的人体模型构建方法探讨基于通用软件的人体模型构建方法探讨 摘摘 要要 本文主要探讨了用通用软件构造人体模型的方法。根据建模方式以及功能上的差异，对各个软件在人体曲面重构过程中的应用进行了合理安排。从人体本身的几何特征、人体与服装关系、建模方式等角度考虑特征点的分布。根据特征点的分布，将人体划分区域，计算各区域内横截面个数。用各软件支持的画线方法进行曲线拟合实验，通过拟合误差比较，筛选出拟合状况相对好的曲线。通过实验比较 u loft 与 uv loft 的不同。设置不同的横截面层数，根据视觉效果、xov 得出的拟合误差数据，分析曲面拟合质量以及不同层数对曲面质量的影响。 试验结果表
2、明当横截面上点的个数为 60 个，按照角度均匀排列时，3ds Max的点曲线拟合状态最好。由于 uv loft 的纵截面曲线要求与横截面曲线上的点建立对应关系，采用 u loft 作为构造人体模型的具体方式。通过对点曲线构造的曲面拟合误差分析，发现横截面上设置 60 点，横截面个数为 60、70、80 时，曲面拟合质量都很好，并且完成了缩减文件大小的目标。从简化操作、缩减数据角度考虑，使用 60 层重构人体模型是优化选择。 关键词：人体模型；曲线拟合；曲面重构；建模；拟合误差 IA RESEARCH ON THE METHOD OF MANNEQUIN MODELING BASED ON UN
