【摘要】 黄河流域三维仿真系统因其涉及的范围广、数据量大、仿真精度要求高而变得异常复杂,为此,系统的总体框架在设计上将需要仿真的三维场景分成两个层次:主窗体层和子窗体层。主窗体层用来仿真全流域大范围的地物信息,子窗体用来仿真局部地区的详细信息以及计算结果的查询演示。主窗体和子窗体的分层解决了当前硬件条件下显示范围大与显示精度高之间很难协调的矛盾,实现了大到黄河全流域整体漫游,小到小浪底电站厂房内的一台机组的全方位、多层次、高精度的三维立体仿真。更多还原

【Abstract】 Three-dimensional simulation system of the Yellow River basin is extremely complicated because of involving wide area, a vast amount of data and high simulation precision. Thus, the overall design of the system needs to divide the three-dimensional simulation into two layers of main window and sub-window. The main window layer simulates geophysical information in a large area of the whole basin and the sub-window simulates the detailed information of local area and inquiry and demonstration of calculation results. The separated layers of main window and sub-window have solved the difficulties of coordination between displaying large area and high precision under the present hardware conditions. It has realized from integrated roaming of the whole Yellow River basin to all-round, multi-layer and high precision three-dimensional simulation of one unit of Xiaolangdi Power Station.更多还原
