Ship Power Station Modeling And Study Of Virtual Concurrent Operations Based On Creator/Vega

With the rapid development of computer technology,communications technology and other related technology, information visualization has become the development of new application, the simulation based on virtual reality is becoming a hotpot of current research. Ship power station simulator is not only an important part of marine simulator, but also a necessary instrument in modern navigation education. It plays an important role on enhancing students'or seamen'practical ability. However, the traditional layout of the simulator is greatly different from real engine room environment, participants"shuttle"in the front of simulator, so it is scaled-down to achieve the desired training effect. The use of virtual reality technology on ship power station not only solves problems effectively, but also has more an more obvious advantages in three dimensional sense , become more convenient,cheaper,easier to upgrade. This paper selects ship power station simulator as studying object and deeply researches ship power station virtual automatic switching based on Creator/Vega, this provides a good reference for other virtual manipulating researches about ship vehicles.Based on analyzing home and ab?? development and application about virtual reality, this paper combines ship actual situation and sets up ship power station virtual switching manipulating system based on Creator/Vega. Including a three dimensional solid modeling,virtual roaming, it achieves virtual,real time and interactive switching. Material jobs include following sections:1.Through the application of virtual reality technology application at home and abroad and the development of ship power station overview, it expatiates the meaning of this subject and puts forward the design project and implementing way about ship power station virtual switching manipulating system.2.The use of three dimensional modeling software MultiGen Creator of ship power station simulator modeling, it makes use of the texture mapping technology,the external reference technology,DOF technology and a number of ways in the process of modeling. After setting up the scene database, it adopts the technology of reducing the number of polygons to optimize models from various aspects.3.It analyzes and researches the mathematical model of generators parallel operations and ship power station automatic approximate synchronous switching characteristics.4.The use of Vega Real-time three dimensional visual simulation software for the roam of engine room and the maneuver of virtual switching, it describes the process of implementation detailedly.The successful development of the system shows the feasibility of virtual ship power station manipulating. The circulating circs of virtual reality technology to ship power station operation is three dimensional,intuitive and real time, it will reduce the labor intensity of students and improve the accuracy and security of manipulating.
