Development of three-dimensional visual and interactive system in the CBTC simulation

This paper discusses the necessity and main methods of developing the three-dimensional visual and interactive system. Then the method of combining OpenGL and 3DS MAX is chosen to build the system. System structure, data transmission and interaction were presented with UML. The realization of dynamic model, viewpoint control, real-time display and vanish and other techniques are studied to ensure this system will satisfy the requirements of real-time displaying and testing of the whole CBTC system.
