Sorry for the delay in my answers. I seldom read this newsgroup...

  It depends on what else you want to do to it. The easiest way would be:

camera
{ location 0 look_at z
  rotate SpinAroundAngles
  translate CameraLocation
}

  You can use vrotate() to achieve this. For example:

#declare CameraLocation = -z*DistanceFromOrigin;
#declare CameraLocation = vrotate(CameraLocation, CameraRotation);
camera
{ location CameraLocation
  look_at 0
  translate CameraTranslation // or ObjectCenter or whatever
}
#declare CameraFinalLocation = CameraLocation+CameraTranslation;

  Now the vector CameraFinalLocation indicates the location of the camera in
space.

: I haven't explored thing like
: vector functions yet.

  You should. They are very handy.

  You mean Teemu, Jari and Saku?
