摘　　要：在一般的视景仿真应用中,通常只是对特定模型在给定场景下的仿真,显得过于单一性和针对性。随着视景仿真的迅速发展,视景仿真平台的开发过程要不断面向多用户的多需求,以往的技术会加大开发成本。为了方便快捷对仿真任务进行开发,利用VegaPrime和OpenFlightAPI对模型进行实时在线编辑,对仿真任务的细节进行编辑,并将编辑后的模型直接用于仿真任务,设计一种面向多用户的视景仿真平台系统。此平台综合运用了视景仿真、数据库、网络传输、多通道显示拼接等多种技术,具有一定的通用性,简化了仿真任务的设计过程,很大程度上提高了仿真任务设计的效率。In common scene applications, usually the geometry models and the scene are fixed and cannot be edited online. Therefore, the simulation procedure is a little simplex and cannot be applied to other applications without modification. With the rapid development in scene simulation systems, scene simulation methods are facing multiple users＇ multiple requirements, however previous development method will cause high cost. In order to fasten and simplify simulation development procedure, a kind of multi-user scene simulation system was developed. In this system, VegaPrime and OpenFlightAPI were used to edit the geometry models and the simulation task online, then the models were directly input into the simulation tasks. Visualization simulation technique, database method, network communication and multi-tiled display systems were integrated into this system. The system provides a kind of universal method, which not only simplifies the design procedure of simulation tasks but also improves the design efficiency of simulation tasks.
