| 摘 要： | 三维实体的开发与控制是构建虚拟现实仿真环境的关键,对此进行了研究.给出了基于OpenGL三维实体的具体建模方法,包括规则实体合成,曲面实体的合成,三角形合成以及实体在场景中的六自由度控制法.以导弹为例详细描述了相应的编程实现过程.已被用于某实时空情仿真系统,在复杂场景中帧速率可达50fps以上,场景中模型的响应速度,逼真度和运动效果都达到了项目预期的要求.使用结果表明该方法所建模型在实时性,交互性,兼容性上具有明显的优势.

| Abstract: | During virtual reality simulation,developping and controlling 3D entities is a key technology to construct a virtual environment.Three building and displaying methods of 3D models based on OpenGL are analyzed and presented,colnpounding of regular entities,curved surface entities and triangle entities and motion control of degree of freedom are discussed.Taking a missle modeling for example,the process of programming is described in detail.These methods has been used in a simulation system of real time air defence system with 50fps.The model's responding speed,fidelity and movement effect as were expected.Result of usage indicates that the medeling method with OpenGL have obvious advantages in real-time,interaction and compatibility. |
