Abstract


With the Chinese high-speed railway undertakings the vigorous development of , virtual reality technology and rail traffic the field of combined with is also more and more closely . Trains Depending on Scene Simulation System then the is one of the a application of , it not only be able to applicable to Yu aircrew compiled cart, operation monitoring , line laying of and other complex engineering projects , the same time also for the trains the driver provides a good training platform . Against the the existing trains middle different lines , trips the situation , the train visual simulation system of better able to achieve line transplantation, its security, economic , repeat the advantages of , is being train running Management is playing an increasingly big role. Trains Depending on Scene Simulation System middle , depending on the King modeling is the the most important part . This paper, In the through the sight scene simulation correlation technical theory analyzed, and combined with trains relevant drawings and along the line acquisition material , choose the of a professional visual simulation Modeling Software Multigen Creator As a the train visual Keng modeling the main tool . This article through the Multigen Creator focus of introduces the the train simulation modeling that are involved in to the 's related visual King technical ; and to use of its modeling idea , focusing discussed the train simulation modeling the contents of the and steps. This article fully discusses the train running environment under the of the model objects , and formed a the model cell database . Against the model unit , this article will train visual Keng modeling is divided into trains correlation and scenes related two part of the , and through the and meticulous classification will be model unit one by one parse and to be realized . Through pairs of each model unit is generated independently , via the multi-level the integration of , and ultimately to achieve train running environment Large-scale Orography , large scene 's build ; and leverage some peculiar to modeling technology will be train running in the Controllable the model unit separation come out , available for scenes -driven and functional editing module invoked. This article build of the train runtime environment fine, lifelike , the application of technologically advanced, conform the train visual simulation requirements. This article Finally respect of train running scenes fast, randomly generated put forward based on the model cell database approach. This approach better able to to achieve massive scenario In three-dimensional environment under the quickly build , and for the the scene middle model unit to achieve randomly generated , an excellent way to reflects the the train visual scene simulation system at different lines, vehicle trips under the can be transplanted properties.
