质量弹簧模型在外科模拟中的实现与应用

Realization and application of mass -spring model in chirurgic simulation

近些年来,对用于外科手术实时仿真算法的研究得到了飞速的发展。本文中作者首先简单地介绍和比较了目前得到广泛应用的两种用于模拟形变物体的建模方法。然后通过具体实例．笔者介绍了如何建立基于质量弹簧方法的模型以及模型的网格化。接着笔者给出了一个用于系统实时仿真的类静态模拟器的算法,包括如何对模型进行假设,以及用于简化计算的重要算法:QSS算法。最后笔者对本文做了总结,并展望了这种算法的应用前景。

In these years, the algorithms research in chirurgic real.time simulation system has developed very fast. This paper firstly presents a briefly introduction and comparison of two widely used methods for animating deformable objects. Then with the examples it introduces how to generate a model which is based on the Mass-Spring method and meshing of the model, After that it describes quasi-static simulator that can be used in chirurgic real-time simulation, including assumptions of the model, and the algorithms for computing reductio n： QSS. At the end there is a conclusion of this paper and it describes the application prospect of this model.
