本课题的研究目标是开发具有良好逼真度和实时性的虚拟手术人体软组织变形模拟方法。本文提出了一种将质点-弹簧模型与基于压力的方法相结合的软组织变形模拟新方法。此外，我们还基于质量-弹簧物理模型，使用OpenGL 3D图形标准构建了虚拟角膜变形系统。然后讨论了软组织变形的动力学模型及其数值积分算法。利用这种建模方法，我们完成了角膜组织的变形仿真，并分析了我们的方法的仿真结果。
Our research aims to develop methods with good fidelity and real-time nature for deformation simulation of human soft tissue for virtual surgery. In this paper, we propose a new method for the deformation simulation of soft tissue by combining mass-spring model with pressure based method. In addition, we build a virtual cornea deformation system using OpenGL 3D graphics standard based on mass-spring physical model. Then dynamic model of soft tissue deformation and its numerical integration algorithm are discussed. Using this modeling method, we complete the deformation simulation of cornea tissue and analyze the simulation result of our method.
