基于骨架关节点约束的交互式局部变形
Interactive Local Deformation Based on Skeleton Joint Point Constraint
摘要
Abstract
This paper presents a interactive local deformation method based on skeleton node constraint by using generalized meatball deformation.The method extracts the skeleton nodes of the polygonal mesh models, employs the skeleton structure to determine the local field which the skeleton nodes influence.It computes the Euclidean distance between mesh vertices and skeleton nodes.The maximum Euclidian distance is constraint radius, calculates the potential function for these vertices.The update position of the mesh vertices is computed by handling the space coordinate of the skeleton node.Experimental results show that the method can maintain the local feature of the polygonal mesh models and guarantee the intuitive and efficient of model deformation.关键词
