动态地形的实时可视化

Real-Time Visualization of Dynamic Terrain

针对动态地形可视化中的特殊需求 ,提出了分辨率的动态扩展技术 ,并给出了实时可视化动态地形的完整解决方案 .该方法既消除了地表网格模型中的不连续问题 ,又能很好地表现地形的形变效果 .

In most published papers on visualization of terrain, the object of research is the static terrain. And the methods in these papers can't be directly used for visualizing the dynamic terrain. To meet the special requirement in visualization of dynamic terrain, a technology which is called dynamic extension of resolution is proposed. And the complete solution to visualize the dynamic terrain in real time is given. It both eliminates mesh discontinuities and represents the deformed region well in terrain model. Examples illustrate practicability and efficiency of the method.
