Research Of 3D Modeling In Train Operation Scene Simulation

As the high speed railway prospers, virtual reality has become closely related to railway transportation. One application is scene simulation. It can provide simple solutions for train grouping, operation monitoring and railway pavement, and also give a sound platform for training operators. For different routes and trains, railway scene simulation system helps design and build routes. Because it's very safe and economic, it is being vastly used in railway operation management.Scene modeling is an important component in scene simulation. This article chooses professional simulation tool Multigen Creator via analyzes relevant techniques with real design blueprints, real ambient terrain. Through Multigen Creator, we discuss modeling content thoroughly step by step. After the discussion of train operation environment, we move on to modeling unit database. For this subject, this article divides scene modeling into two parts:the train and surrounding environment, and analyzes each small section. Through building models independently and combining several layers, the final ambient terrain and train can be obtained. Special methods are used to isolate interactive units in train modeling, so that they can also be utilized in scene driving and functional editor. The train models and ambient terrain in this article are precise and realistic. They satisfy professional scene simulation's requirements.In the end, this article brings up a new idea for rapid and random generation of train operation scenes, which is based on the modeling unit database. This method can quickly build giant scenes, and randomly build models in this scene. This is a perfect example of the portability of scene simulation for different routes and trains.
