基于OpenGVS的三维仿真软件的开发研究

视景仿真技术是在数值仿真的基础上以图形和动画来显示仿真的过程和结果，近年来视景仿真技术在军事领域上得到了广泛的应用。OpenGVS是专门用于实时3D图形开发的软件。该文在Multigen Creator 3D场景建模的基础上，采用OpenGVS来实现场景驱动，开发了一个导弹与飞机交战场景的仿真程序，并介绍了实现三维动画驱动时需要解决的几个关键问题，包括外部模型的导入，视点的选取，碰撞的检测，以及爆炸效果的产生等。这些技术的运用使得软件仿真的效果更加逼真。

Research on 3D Simulation Software Based on OpenGVS

Scene simulation technique displays the simulation process and results using graphics and animation based on numerical simulation. Scene simulation is widely used in military fields in recent years. OpenGVS is a real-time scene management software for 3D application developers. This paper develops a simulation program of belligerent scene between missile and battleplan, and adopts OpenGVS to realize the animated driving, the simulation modeling software of Multigen Creator to create the required 3D models. The key techniques of the program are introduced in this paper, i.e. the selection of viewpoint, collision detection and the effects of explosion, etc.. the result of the simulation is more realistic.
