摘　　要：运用OpenGL的建模、光照、材质、雾化等技术,实现集装箱堆场的仿真,获得效果良好的三维真实感图形.主要建模对象包括集装箱、堆场、海平面和雨.通过控制堆场的顶点来控制堆场的形状,并提出通过判断俯视图是否相交来进行堆的碰撞检测的方法.在粒子系统的基础上,探讨风雨模型的可视化,提出以线元来为基本造型单位构造风雨场景,通过漫游、雾化、纹理映射等技术,进一步增强堆场的三维真实感.Using the modeling,lighting,material quality,fogging and other technologies of OpenGL,we have achieved a good effect 3D simulation graphic of container yard,which main modeling objects include containers,yard,sea level and rain.We propose a approach to control a yard＇s shape by controlling its vertices,and to detect if two piles are intersected by judging the relation of their top view.At last,we discuss the wind and rain model visualization based on particle system,and proposed a method to accomplish the rendering of rain and wind by line based on rendering technique.Practical use of the system shows that the application of navigation,fogging,texture mapping technology can strengthen the reality of yard.
