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
