i was wondering what the best way to create light trails would be?
(like this example http://i1.treklens.com/photos/7195/jhbskylinerings2.jpg)
i figure if it was an animation, i would just open the shutter and have the light move, but if i were to do a single frame shot, how would you do it?
would it be best to just create a curve/polygon and put some sort of incadescent shader on it? or is there some way just to draw a curve and have maya or whatever i was using for rendering to calculate it.
thanks for any advice you can give.
