Abstract: To conquer the insufficiency of peculiar functions of simulation platform——Vega, customized modules should be extended. The work in this paper is based on the deep research and analysis on Vega system architecture and one of the dynamic modeling techniques——particle system, and it extends Vega FX module using OpenGL, Vega API and Open Performer API. The extended modules are compatible with other modules in Vega and strengthen the functions of Vega

摘要： 针对仿真平台Vega 在实现特定功能方面的不足，需要扩展自定义模块。基于对Vega 体系结构和粒子系统不规则物体建模技术的深入研究，采用OpenGL 三维图形库、Vega API 和Open Performer API 对Vega 的特效模块进行了扩展。扩展模块与Vega 中的其它模块完全兼容，从功能上进一步完善了Vega。
