I think the OP meant that POV images can be "zoomed in" without any loss 
of detail. This is obviously not the case in real photographs.

That is hardly a surprise as POV images are made from mathematical 
models that don't necessarely have any precision limits. There is also 
no contrast reducinbg MTF involved so one can just create any kind of 
close up. The only limit is probably the accuracy of floating point numbers.
