   where in the coordinate space should I draw the scene[opengl]
  is it normal to translate the scene so the corner of it starts at 0,0,0 of the world view? I've been messing around with a little program for a few days and I have drawn my scene around 0,0,0 but when Im doing animations I have to check if things are going on on < 0 or > 0 of the world... and I was just thinking maybe its easier if I move it so Im working in one part of the coordinate system? whats normal practice? Hope all this make sence now :p   
  it's usually always orientated around the origin to preserve precision, you should never need to check if a vertex (x,y,z) is < 0 or > 0 when doing animation anyway. what are you animating? how are you animating it?   ;  Didn't check back here.. yeah, found out I was animating it wrong..
