摘要
针对实时虚拟手术仿真中的弹性形变物体，本文提出了一种新的算法。该算法考虑到虚拟手术中存在的特殊情况，在形变模型的实时交互性与精确性之间取得了良好的平衡。模型的实时交互性是通过进行预处理实现的，此时响应用户操作的实时形变计算得到加速。模型的精确性则来自于基础算法有限元法的精确性。
In this paper, an algorithm is presented for elastic deformable objects suitable for real-time virtual surgery simulation. This algorithm considers the special conditions within virtual surgery, and has a good balance between real-time interactivity and accuracy of the deformable model. Its real-time interactivity is gained through pre-computing some data to fasten the calculation of deformation in real-time response to user's inputs. Its accuracy comes from the accuracy of the Finite Element Method (FEM), the base of this algorithm.
