摘要
触觉可视化技术的出现开辟了虚拟现实技术新的应用前景,柔性物体变形技术成为其中的研究热点。论文对触觉可视化技术中柔性物体变形技术进行深入研究,系统地讨论了基于几何的力变形模型与基于物理意义力变形模型,分析了相关模型的基本思想和优缺点,对这些建模方法的性能进行了细致的比较。结果表明随着硬件技术的不断发展,基于物理意义的有限元模型将会得到越来越多的应用。最后对柔性物体物理形变建模的未来发展趋势做了探讨。
The emergence of haptic rendering opens up the applications of virtual reality technology in which the deformation of soft objects has become the focus. The research of deformation of soft objects in haptic rendering which includes the geometric - based model and physically- based model are given in the paper. Also the advantage and disadvantage of these models are presented. Then, the comparison of these methods is carried out and the results show that the physically - based finite dement model will be used more and more according to the development of the hardware technology. Finally, the future investigation of modeling is discussed in the paper.
