Virtual liver modal rending and cutting is an important topic of virtual surgery and has important guiding significance for clinical surgery. Modeling a virtual liver is put forward, moreover lapped solid texture is applied to the body of liver and real-time visualization of cutting is achieved. At last, some simulation results of liver are proposed. The result shows that the method can meet the virtual surgery on the liver real-time rendering and cutting requirements and has a certain value.%虚拟肝脏模型的绘制和切割是虚拟手术研究的一个重要课题,对临床手术具有重要的指导意义.论述并设计了一种虚拟肝脏建模方法,将重叠体纹理应用到肝脏体上并实现切割的实时可视化,给出了肝脏绘制和切割的实验结果.结果表明,该方法能够满足虚拟手术对肝脏的实时绘制和切割的要求,具有一定的应用价值.
