基于Vega的通用面向对象仿真程序

Vega已经成为视景仿真领域的主流开发工具，但其提供的API是面向过程的，为大型仿真系统的开发带来很大的复杂性，且程序的重用性很低。基于Vega的视景仿真系统在结构上有很大的相似性，且大部分程序代码具有通用性。该文结合Vega提供的接口和基于Vega的视景仿真系统的特点，将这些接口进行面向对象的封装，并提供一种通用的面向对象程序框架。

Universal Objected-oriented Framework of Vega-based Simulation Program

Vega has already become the common development tools in the scene simulation, but the API of Vega is process-oriented. It makes the development of large-scale system very complex and the reuse of the code very low. By analyzing different Vega based scene simulation systems, these systems have great similarities in program structure and commonability in the code. This paper combines the interface that Vega offered with characteristic of scene simulation and encapsulated the interface progressively to make it have the properties of objected-oriented, and offers a kind of common program structure.
