Three-D garment design based on components and interactive genetic algorithm

为提高三维服装设计效率,降低专业性要求,提出一种基于部件库及交互式遗传算法的三维服装设计方法.设计适用于遗传操作的三维服装部件数据结构,并利用参数化建模方法构建了典型三维服装部件库;在此基础上,提出基于部件指针的遗传算法编码方式,使之适合于三维部件的遗传操作,并建立三维部件操作的6种约束机制以保证遗传操作的正确性;另外,对服装部件分别评价的交互方式更能准确地获取用户对服装的适应度评分.实例表明,交互式遗传算法与三维服装设计的有机结合,使三维服装设计更为简易、高效,具有更好的实用性.

To improve the efficiency of the 3D garment design and reduce the professional requirements,a new 3D garment design method based on components and interactive genetic algorithm was proposed.Special data structures for 3D garment components were designed to fit the genetic operation.A 3D component library contains of typical 3D garment components was built by parametric modeling methods.Then,a new chromosome encoding method based on component pointer was proposed for the genetic operations of 3D garment components.Moreover,six types of constrains were introduced to ensure the genetic process correct.In addition,we introduce a mechanism for users to evaluate the garment components separately,and thus,the fitness rating value could be acquired more accurately.Experiment results shows that our method is more feasible and applicable.
