Multigen Creator

This paper designed the design scheme of a visual simulation system for tower cranes, and described the methods of modeling scene and manufacturing texture according to the characteristics of Multigen Creator software and Vega virtual software. The five model optimization techniques including levels of detail technique, instancing technique, removing redundant faces, billboard technique and external reference were discussed in the modeling process. In order to improve system running speed, the methods of reducing the face number of the models and save memory spaces were investigated. Scene driving was realized in programming environment of VC++ software. Finally the scene modeling and driving of visual simulation system for tower cranes were completed.

Training Efficiency

Abstract UAV-borne missile is effective weapon to attack enemy ground targets. It is expensive, costly and difficult to live-fire drill. Using virtual training instead of actual training can greatly improve the training efficiency and the combat effectiveness. The article regards the operation training of a certain type of UAV-borne missile shooting training as the research object, based on the development of a visual simulation system for UAV-borne missile, uses the object-oriented design method to design a virtual training system based on LabVIEW. The system can realize the shooting operation training of trainees in a virtual environment, and achieve the goals of reduce training costs; improve training efficiency and shorten training period.
