针对虚拟试衣中布料各向异性的特点,提出了一种基于几何变形能模型的布料动态模拟方法,该方法较好地保留了布料的几何特征,实现了布料在不同材质效果下的行为。我们首先构造了一个包含顶点位置、边长、二面角和引力的客观形变能,然后在最小二乘意义下进行了数值求解。为了建立织物变形的动态解,通过对比典型真实织物的真实照片,进一步分析了几何能量项前面的不同权重与材料性质的对应关系。建立一种动态权重调整方法可以为数字家庭中的虚拟试衣应用模拟相似的布料各向异性行为。实验表明,该方法有效地提供了更加丰富的布料变形效果和鲜明的材质效果。
According to the anisotropic property in most real-world cloth for virtual fitting, this paper proposes a novel dynamic cloth simulation method via geometric deformation energy model that preserves geometric features well to achieve cloth behaviors with various material effects. We first construct an objective deformation energy with the terms including vertex position, edge length, dihedral angle, and gravitation, then we conduct a numerical solution in the least square sense. In order to establish the dynamic cloth deformation solution, we further analyze the corresponding relationship between different weights in front of geometric energy terms and material properties by comparison with the real photographs of typical real fabrics. Establishing a dynamic weight-regulation measure can model similar cloth anisotropic behaviors for virtual fitting applications in digital home. The experiments show that our approach effectively provide more rich cloth deformation results with distinctive material effects.
