   "trail" using glsl
  Hi! been doing a particle system (quads with textures) in openGL, now I want make it look like trails behind the particles. Havent used shaders before, is that a good way of making a trail? Would be cool if anyone could point me in the right direction.. =)   
  Might help if you are a little more specific by what you mean when you say "trails."It might be possible with shaders.  What about just using more particles (maybe a different texture) to create the trail?   ;  draw a quad/quadstrip behind the particle in the direction its moved, shaders are irrelavant to the effect   ;  He might just be looking for how to do a motion blur effect? tossin it out there just in case   ;  yes motion blur is kind of what I want, however I dont want the whole scen to blur, only the particles.. can this be done?   ;  post a screenshot of what u want to do (from another game)
