摘要/Abstract

摘要： 形变仿真是计算机图形学、系统仿真、虚拟现实等领域的关键技术,但在现有物体形变研究中,将自然交互引入三维弹性物体变形的研究较少。针对该问题,引入触觉交互至形体编辑领域,在给出视-触觉同步的自然交互框架基础上,提出了一种基于触觉交互的弹性物体变形仿真算法,包含建立栅格层次结构、构建局部“质点-弹簧”系统和数值迭代动态仿真。实验结果表明,该算法运行稳定,鲁棒性好,能实现视-触觉同步交互感知体验和良好变形效果,且整体交互过程简单、自然和有效。

关键词: 虚拟现实, 触觉交互, 实时形变, 质点-弹簧模型

Abstract: Shape deformation is widely used in virtual reality, system simulation, computer animation and other graphics applications. Few people pay attention to introducing haptic interaction into 3D model deformation. We provide a haptic interactive framework by introducing haptic interaction into shape editing field. Based on the above haptic interactive framework, we propose a 3D model deformation simulation algorithm based on haptics. In order to realize the shape deformation, this algorithm needs to involve three parts: grid hierarchical structure, local mass-spring model and the dynamic shape deformation. Experimental results show that this algorithm has good stability and strong robustness, and the method can enable operators to perceive and deform the 3D model through haptics interaction. In addition, the entire interactive process is simple, natural, and effective.

Key words: virtual reality, haptic interaction, shape deformation, mass-spring model
