   getting polys to face camera
  How do i get a polygon to face the camera if I use gluLookAt?I know how to do this if the polygon only needs to rotate about 1 axis (I just use the dot product), but if it requires other rotations then it doesnt work.I realize that if you keep track of the camera''s rotations, then you can just reverse them later, but what if I dont keep track of this?  
  type "billboarding opengl" into www.google.com    http://members.xoom.com/myBollux  ;  that worked, thanks!
