摘要
OSG(Open Scene Graph)是一个出色的视景仿真开源软件包,基于OSG可以开发高拟真度低费用的飞行视景过程。但是由于OSG是基础类库,因而有必要对其进行二次开发以降低视景过程的开发难度和开发周期。首先论述了OSG的体系结构,并依据装配式的视景仿真生成思想,设计了基于OSG的飞行视景仿真软件平台FSS的顶层结构体系。基于该顶层设计,实现了软件的开发,通过示例可以看出,在FSS上可以简单、快速实现飞行视景过程的创建,从而大幅度降低了飞行视景仿真过程开发的周期和难度。
Open Scene graph （OSG） is an open source toolkit, and it can be used to develop high fidelity and low cost flight scene simulation. But because OSG is a fundamental library, it is necessary to further develop it in order to reduce the difficulty and cycle of exploiting flight scene simulation. The paper firstly discusses tbe structure of OSG, then presents in detail the way of putting forward flight scene simulation by resource assembles, and the top - level design of flight scene simulation （FSS） platform based on OSG. According to this framework, the platform of scene simulation is implemented. The example shows that flight scene simulation can be realized quickly and easily on FSS.
