摘要
可视化技术用于触觉再现显著加强了力触觉再现的交互性,具有广阔的应用前景。触觉可视化的显示效果很大程度上取决于虚拟物体建模方法和受力变形的计算方法。文中以类椭球体作为研究对象,选择有限元方法,进行了物理建模和变形计算,并利用VC++对ANSYS进行二次开发,设计了类椭球体变形显示软件。实验表明该软件可视化程度高,交互性好、显示效果真实,为柔性物体可视化触觉再现系统的深入研究奠定了基础。
Visualization technology can improve the interactive performance in haptic representation,so visual haptic representation has great prospects in application.The effect of display is highly decided by the modeling and deformation calculation algorithm.This paper selected a resembling ellipsoid and researched its modeling and deformation calculation with finite element algorithm,and desighed the software to display its deformation by further exploitation of ANSYS with VC＋＋.Experiments show that this system has such advantages of high visualization level,nice interactive performance and good display effect,and it can be the foundation of further research in visual haptic representation with soft objects.
