osg粒子系统 雨雪交加的效果 粒子系统的模拟过程-osg particle system

osg天气,osg利用封装在OPENGL的粒子系统，设计的天气系统，将雨和雪的情况反映出来-osg weather, osg OPENGL using encapsulated in the particle system, the design of weather system, rain and snow conditions will be reflected in

osg园区视景仿真，实现小车碰撞检测，粒子效果，键盘控制局部窗口，文本显示功能，程序在VS2013下配置osg3.4实现-OSG Park visual simulation, car collision detection, particle effects, keyboard control of local windows, text display, the program in the VS2013 configuration osg3.4

基于osg的火焰粒子效果，可自行更改为其他烟雾等效果。(Flame particle effect)
