An Application Of Virtual Reality Technology In The Visual Simulation System Of Roaming Engine Room

With the rapid speed development of computer science, communication technology and other technologies, the visibility of information becomes the new field of application development and the simulation technology based on Virtual Reality (for short , VR)is being increasingly the focus of currently research. This paper presents the process of how to analyze the status of the development and application of VR technology, models the virtual engine room system according to the real engine room condition, sets up the 3D static model and active model, and develops the visual simulation system which has the VR characteristic. The research work includes several parts as fellow:The significance and importance of this task is presented by carefully studying the status of the development and application of VR technology all over the world. The method of how to develop the virtual engine room system is also presented in this paper.A software named MultiGen which is based on SGI workstation is used to model the scene of engine room. In the process of modeling, the method is mostly based on graphics, which includes the solid models, sound models, active models and background models. The key technology of the software relating to the characteristic of modeling visual engine room is finely illustrated. After set up the scene database, the models are well optimized.Real-time roaming is fulfilled by using a VR development software named Vega and the design process of scene roaming is offered. The key technology of collision check-up and interactive control are also illuminated in this paper.
