摘要
提出了地形环境下的动态场景绘制流程。使用空间离散化的方法实现了运动物体之间以及运动物体和地形之间的快速碰撞检测。为了实现运动物体与地形的匹配,采用了一点匹配法和面匹配法。实现了网格模型、基于图像的模型在地形环境下的绘制。最后给出了坦克和虚拟人在地形环境中绘制的实验结果。该方法可应用于网络游戏、战场视景仿真、数字城市、电影制作等领域。
The rendering of dynamic scenes in terrain environment is studied. The flow chart for the rendering is suggested. The spatial discretization method is used to detect the fast collision among moving objects and collision between moving objects and terrain. The point matching and face matching method are utilized to realize the matching between moving objects and terrains. The mesh models and image-based models are used to map tanks and virtual humans. Experimental results show that the method is effective.
