   Can anyone recommend a good particle engine tutorial?
  Hi,I've been coding a particle engine for a little while in my spare time, its come along great, but the more I look at it the more I see fundamental problems with it, if anyone could recommend a good tutorial using OpenGL for me to read and work with I'd be extremely grateful, something that works from scratch as I think a re-code would be the best option for me at the moment.-Aura   
  Sorry, but bump...-Aura   ;  It's not openGL, but it definitely explains very well how a particle engine works: http://flashgameu.com/podcast/flashgameu_com_video_tutorial_simple_particle_system.html
