【摘要】 使用实时三维建模软件MultiGen Creator建立油气集输过程三维模型的等级数据库结构。针对因模型容量过大而降低交互速度这一问题,采用分组LOD和Creator绑定Vsimplify插件技术,利用Garland简化算法和三角化算法对模型进行优化,同时采用模型拾取技术,使仿真培训效果逼真,交互速度快。操作人员可以从任意距离和角度观察油气集输的各个过程,了解生产设备的内部构造及生产环节的动态运转过程。更多还原

【Abstract】 The database hierarchy structures of three-dimensional models of the process of transportation and storage of oil and gas were constructed using MultiGen Creator. The technique of Group LOD and Vsimplify bound to Creator, brief Garland algorithm and triangle algorithm were adopted to optimize the models; therefore the problems of low man-machine interaction speed due to large model volume were solved. The model pickup technique was used to enhance the interaction speed and to make the simulation training more lively. By the simulation training system, operators can observe the process of transportation and storage of oil and gas from arbitrary distance and angle through the terminal and can also observe the inner structures and dynamic operations of the equipments.更多还原
