| 摘 要： | 作战仿真是作战方案实施前利用计算机模拟技术对其进行检验的一种重要手段，而视景生成主要是使仿真过程直观形象，增加可信度，是仿真过程中必不可少的应用技术。提出一种基于分形技术的多层次细节视景仿真方法。主要思想是利用LOD生成初始景观的三角形网格，然后用分形技术进一步对三角网格递归细分，解决了不同细节层次区域间的视觉过渡，最后经过视景渲染，生成逼真的三维视景。对其应用效果和性能评估表明，该方法能提高视景仿真系统的整体性能，具有一定的军事价值。 |

| Abstract: | Battle simulation is an important method for testing battle project of using computer simulation technology before executing it.View-scene generating can make battle-simulation visualization and reliable,it is a necessary technology in simulating application.In this paper,A visual simulation method based on LOD and fractal technology is proposed.The master idea is generating initial triangle grids for view-scene using LOD technology,subdividing triangle grids using iterative fractal technology,which resolves visual transition problem for different detail region,and getting vivid 3D view-scene by doing visual rendering.Simulation result shows the method can improve the capability of visual simulation system and has been important value in battle command. |
| Keywords: | Battle simulation View-scene Layer of Detail Fractal |
