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。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 3 D 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 3 D 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 3 D model through haptics interaction. In addition, the entire interactive process is simple, natural, and effective.
