摘　　要：为提高渔船操作模拟器视景系统的可视化效果,提出并实现了一种基于物理模型的三次B样条插值曲线绘制渔网和手纲的方法;考虑到可视化系统的实时性,通过简化网具系统的几何模型,构造三次B样条插值曲面实现了基于物理模型的B样条插值曲面的渔网可视化;根据视点距渔网的远近分别调用B样条插值曲线和B样条插值曲面方法进行渔网建模,从而既提高了系统的实时性,又保证了绘制渔网的逼真度。A method of visualization of fishing net and bridle with cubic B-spline interpolation curve and surface based on physical model was proposed and realized, which improved the visualization of scene simulating system of fishing simulator. Considering the real-time visualization, a method of visualization of fishing net with cubic B-spline interpolation surface based on physical model was realized by simplifying the geometric model of fishing net. According to the distance from viewpoint to fishing net, B-spline interpolation curve and B-spline interpolation surface method were called for the fishing net modeling, which improved the real-time and realism visualization of fishing net.
