摘　　要：考虑绘制动态地形的高逼真性与实时显示的突出矛盾,结合实时优化自适应网格(ROAM)地形绘制算法与Seamus McNally对该算法误差度量的改进,提出了动态地形可视化系统框架,初步设计并实现了仿真环境中炮弹等仿真实体与地形交互的碰撞检测。实验证明了该方案的有效性与可行性。Considering the contradiction between the high fidelity and real time of terrain rendering, real-time optimally adapting meshes （ROAM） algorithm developed by Mark Duchaineau and Seamus McNally＇s improvement to the ROAM algorithm were introduced. Then the system framework of rendering dynamic terrain was put forward. The collision detection between the entity in the virtual environment and the surface of the terrain was designed and implemented prehminarily. The final experiment testified the validity and feasibility of the scheme.
