我们提出了三种基于线弹性理论和有限元建模的物理模型，非常适合于手术模拟。第一个模型结合了预先计算的变形，实时变形大尺寸的网格，但不能对网格进行任何拓扑更改。第二种模型类似于弹簧-质量模型，其中体积变形和切割操作可以在小网格上以真实的时间进行模拟。最后，我们开发了第三种方法，将前两种解决方案结合到一个混合模型中，模拟复杂解剖结构的变形和切割。
We propose three physical models based on linear elasticity theory and finite-element modeling that are well-suited for surgery simulation. The first model combines precomputed deformations to deform large size meshes in real-time, but cannot make any topological changes to the mesh. The second model is similar to the spring-mass models where volumetric deformations and cutting operations can be simulated on small meshes in real time. Finally, we have developped a third method, combining the previous two solutions into a hybrid model that simulates deformations and cutting on complex anatomical structures.
