Sounds like what you want is the equivalent of a 2D array of boxes, with 
each box's height determined by an input image. Do I understand that 
correctly?

POV-Ray currently doesn't provide any native support for such an object 
(except of course an actual array of boxes, a mesh generated by a custom 
macro, or some such). It shouldn't be too difficult to implement such a 
primitive though.
