摘要
结合Open GL和Active X技术,研究了三维装箱的可视化问题,在Visual Studio环境下,进行面向装箱布局的三维显示控件开发。通过接口方法获得货物配载信息,实现货物配载结果的可视化;为了观察集装箱内货物布局,根据用户观察方向与箱壁平面法线方向,判别集装箱箱壁平面是否绘制。以线框形式显示货物,便于查看整体重心和集装箱几何中心的位置,从而判断配载方案的稳定性。控件测试表明,该控件可以根据配载货物的特征信息和位置信息,实现货物配载整体效果显示、货物摆放方式和堆码层数显示、重心显示和货物高亮显示等功能,直观地展示装箱配载结果,便于用户调用、观察、验证和修改装箱布局方案。
3D visualization of the container loading layout is researched by using ActiveX and OpenGL in this pa- per. A visualization control is developed based on cargoes＇shape and location under Visual Studio environment. The stow- age data is obtained using the interface function to render the cargoes in the container. In order to observe the cargoes con- veniently, surfaces of the container near observer are not rendered according to the relationship between the eye - gaze di- rection and the normal of surface. The gravity of cargoes is displayed and then we can predict the stability of entire contain- er. The test results show that the control facilitates users to display the cargoes＇layout involving placement mode, stack number, gravity center, as well as validate and modify the stowage scheme.
