  How do you select whether you want to apply a transformation to a group
of objects as if it was a single object with a common center point, or
whether you want the transformation to be applied to each object individually,
independently of the other objects?

  Anyways, it's quite trivial to apply a transformation to an object in
POV-Ray in relation to a defined local center point:

#declare MyObject = ...;
#declare MyObjectCenter = <centerX, centerY, centerZ>;

...

object
{ MyObject

  translate -MyObjectCenter
  // add local transforms here
  translate MyObjectCenter
}
