Summary:TP391.41; 针对目前虚拟服装变形方法不能有效地解决局部不同程度变形的问题,提出一种基于局部约束的服装变形方法.首先,根据人体特征参数自定义构建虚拟人服装模型,并在此过程中对质点-弹簧模型和欧拉算法进行了改进;其次,对服装质点施加约束力,在质点原始的位置上添加改进的基函数,并引入约束权重来控制基函数的变化,从而求得质点的正确位置,实现局部不同程度的变形.实验结果表明,该局部约束方法取得了较好的变形效果.
Bibliography:As the current virtual garment deformation methods cannot solve the local deformation of different degrees effectively,a method for garment deformation based on local constraints is proposed.Firstly,the garment model based on human characteristic parameters is established,and the mass-spring model and Euler algorithm are improved.Secondly,after exerting constrained force,an improved basis function is added to the original position of the particles,and the new positions are computed through the improved basis function combined with impact factors,thus the varying degrees of deformation are complemented.The experimental results indicate that the method has good performance.
