The Visual Simulation Of Railway Cargo Loading Process

To guarant the safety of railway cargo transportation, the loading and consolidating process of railway cargo is very important. Learning how to load and consolidate the railway cargo by computer-aided instruction (CAI) is urgently needed in today.Based on AutoCAD 2002, Visual C++ 6.0 plotforms and OpenGL technique, with the technique of multi-media and VR (Virtual Reality), a CAI of loading and consolidation process of railway cargo has been developed incorporates text, sound, picture and computer animation.The whole system can be divided into three parts: static information, dynamic display and 3D scene editor. Static information is to show the user some primitive information such as the cargo size, cargo components drawing, loading steps and other specifications. These static informations are basic blocks for dynamic display. The dynamic display is the loading and consolidating process simuation based on AutoCAD 2002 and 3DS MAX softwares. Also the user can control the system through the "add/delete" dialog box. The 3D scene editor consists of importing and exporting 3D objects, the cargo' s texture editor and the viewport transformation. The scene transformation includes the transformation of the background and the.lighting effect. While the view port transformation consists of translating, rotating, tilting and zooming.
