Ever tried to render a several-million-triangle mesh with POVRay?
If you want to trace topography data you run out of memory much faster 
than you think. 

Staying at that example, a 1-million-triangle topography of a planet looks 
not very well unless you add some "artificial" complexity like 
subdivision surfaces. Or, maybe, something these people described 
"addition of large amounts of geometric complexity into models".
