摘要
为了适应现代化航天技术的发展,需要建立先进的数字化航天发射场视景仿真系统来保障和辅助航天发射任务的顺利开展和实施。以某卫星发射场为研究对象,提出了采用基于三维几何模型构建及动态显示技术的虚拟场景创建方法,利用MultiGen Creator和Vega软件平台,并结合C++编程语言,开发出一个完整的交互式航天发射场及火箭发射三维视景仿真系统,并介绍了其系统设计、开发流程及关键技术。系统在实际发射任务中的使用结果表明,系统运行稳定,仿真效果真实流畅,能够实现预计的功能和效果。
In order to be adapted to the development of spaceflight technology, an advanced digital scene simulation system of spaceflight launch site is required to support the implementation of launch mission. Based on a spaceflight launch site, the paper proposes a method to create virtual scene based on 3D modeling and dynamic vision technology, develops a whole interactive scene simulation system of launch site and rocket lauching by using MultiGen Creator/Vega software platform and C ＋ ＋ programming language. Then the paper introduces the system design, development flow and key technologies. In the actual launch mission, the system can achieve expected effect.
