针对虚拟现实领域中特殊天气、战斗等场景中需要雾、雨、云、火焰、爆炸等场景特效来提高场景逼真度与兼顾渲染实时性的问题，提出采用基于OSG的粒子系统特效。本文在分析粒子系统实现原理的基础上，利用Open Scene Graph（OSG）2．8．2开源场景图形开发库建立粒子特效系统模块，从而有效地解决特殊场景中对粒子效果的要求。给出一个飞行场景中降雪效果的示例，通过分析帧速率等指标说明OSG可以快速绘制粒子系统。试验结果表明，基于OSG的粒子特效能够很好地满足虚拟现实中对粒子特效逼真度和实时性的要求。
針對虛擬現實領域中特殊天氣、戰鬥等場景中需要霧、雨、雲、火燄、爆炸等場景特效來提高場景逼真度與兼顧渲染實時性的問題，提齣採用基于OSG的粒子繫統特效。本文在分析粒子繫統實現原理的基礎上，利用Open Scene Graph（OSG）2．8．2開源場景圖形開髮庫建立粒子特效繫統模塊，從而有效地解決特殊場景中對粒子效果的要求。給齣一箇飛行場景中降雪效果的示例，通過分析幀速率等指標說明OSG可以快速繪製粒子繫統。試驗結果錶明，基于OSG的粒子特效能夠很好地滿足虛擬現實中對粒子特效逼真度和實時性的要求。

Special field of virtual reality for the weather,battle scenes,etc.need to fog,rain,clouds,fire,explosions and other special effects scenes to improve the fidelity of the scene rendered with both real-time issues,In this paper talks about the use of particle system effects based on OSG.This paper analyzes the particle system based on the principle,then based on the use of Open Scene Graph（OSG）2.8.2 open-source scene graph developed library built particle effects system modules,addressed the special scene of the particle effects requirements effectively.This paper gives a flying example of the effect of snow scene,by analyzing the frame rate and other indicators described OSG can quickly draw the particle system.The results showed that,based on OSG particle effects satisfy the virtual reality of particle effects requirements.
