基于Direct 3D的动态地形仿真方法研究

Direct 3D-based Research on Simulation Method of Dynamic Terrain

动态地形使虚拟环境变得更加真实,他不仅反映地形对实体的影响,也能体现实体对地形的破坏,同时遭破坏后新地形又能反过来影响实体的行为,真正实现了实体与环境的交互。结合Direct 3D模型数据的开放性、使用的广泛性以及图形处理速度快等特点,探索以他作为图形引擎实现动态地形仿真的方法。并通过实例证明了方法的有效性。

Dynamic terrain makes the virtual reality entironment more reality. It not only represents effects of terrain putting on entity, but represents the breakage of terrain by entity and the effect on entity action. It realizes interaction between entity and entironment. The paper explores simulation method of dynamic terrain Direct 3D- based, because of the characters of Direct 3D in exoteric data - base and high speed graphics management.
