摘　　要：提出一种全新的基于仿真数据的大坝施工过程实时可视化模拟机制;通过数据库动态链接使可视化系统与仿真系统紧密衔接,且施工方案改变时可视化系统能够自动更新,并利用引擎中的表层模块实现数据库的显示与查询,极大地提高了可视化系统的动态性和可移植性;粒子系统模拟施工期导流;不同的地物模型采用不同的建模方法。最后,采用高效的图形渲染引擎OGRE开发出逼真的大坝施工过程三维可视化系统。A new real-time visualization simulation mechanism of dam construction process was proposed based on the simulation data. A database dynamic link and an overlay module of OGRE were introduced. To implement display and query, the visualization system could be updated automatically when the construction program was changed, which has greatly improved the dynamic and portability. The particle system was introduced to simulate division during construction, and different modeling methods were adopted to create various terrain models. In the end, a vivid and dynamic 3D visualization system of dam construction process was developed by the efficient graphics-rendering engine, OGRE.
