长期以来，在水利水电施工计算机仿真领域，仿真过程可视化一直是一个引人注目的技术问题；为了提高仿真软件的易用性，有必要将仿真中显示的图形由二维改为三维，而且要求图形显示具有实时性。根据这个目标，以水工大坝混凝土浇筑施工仿真的可视化问题为例，就实现三维动画显示的软件环境，三维显示算法进行了详细的分析，给出了有关建模、投影、消隐等问题的计算公式及推导过程，并且针对混凝土大坝分块柱状浇筑法仿真的三维动画建模方法及实施手段作出了进一步的讨论，最后给出了混凝土浇筑三维动画显示的实现过程
For a long time, in the field of water conservancy and hydropower construction computer simulation, the visualization of simulation process has been a compelling technical problem. In order to improve the usability of simulation software, it is necessary to change the graphics displayed in simulation from two-dimensional to three-dimensional, Graphical display with real-time. According to this goal, taking the visualization of hydraulic concrete dam pouring construction simulation as an example, this paper analyzes in detail the software environment and three-dimensional display algorithm of 3D animation display, and gives some questions about modeling, projection and blanking Calculation formula and derivation process, and further discussion is made for the three-dimensional animation modeling method and implementation method of concrete block dam pouring method. Finally, the realization process of three-dimensional animation display of concrete pouring is given
