基于物理的可变形模型

Physical-based Deformable Model

应用于计算机图形学中的基于物理的可变形模型借助力的工具以直观自然的方式实现物体变形,相对于传统的纯几何模型有更广阔的应用范围。本文介绍了几种典型模型的基本思想和应用情况,分析了它们的特点、采用的简化计算技术,以及各自存在的问题和局限性。最后指出了要想理想解决物体可变形建模问题所必须进一步研究和突破的若干关键技术。

In computer graphics, physical-based deformable model presents an intuitive way to deform objects by using the concept of force. It can be applied in wider field than the pure geometry model can. In this paper, the main idea and applications of some popular models are introduced. The advantages, limitations of these models as well as the related technology of reducing computation time are analyzed. We also suggest some important areas for future research in conclusion section.
