摘要:

针对三维人体曲面特征,采用离散高斯曲率计算公式,对有限元技术网格化的衣身原型曲面上节点的高斯曲率进行计算,并以0.005为界限值来划分可展与非可展曲面。基于蚁群算法原理,根据衣身原型曲面节点分布特征,设计算法,动态调整各蚂蚁面临的可选节点集Q和禁忌表tabu,并以各区域结点所占百分比为评价指标,结束蚂蚁循环,最终确定出最佳路径,从而实现衣身原型曲面的可展区域与非可展区域的划分,其结果与人体曲面分布规律符合度较高。

Abstract:

According to the character of 3-D body surface, the method for calculating discrete Gauss curvature is used to get Gauss curvature of different nodes from basic body surface, whose gridding is affected by using the finite element technique. Take 0.005 as limited value to divide the whole surface into developed and undeveloped one. Based on ant-colony algorithm, a new algorithm is designed according to the distributing character of nodes in the surface. In the new method,the selected nodes collection Q and tabu are adjusted dynamically and the percentage of every area nodes accounts for is taken as evaluation index to end the circling for every ant. Finally the optimum route is got and the basic body surface is divided into developed and undeveloped one. The result is with distributing rule of body surface.
