The creation of the optimized rep. It has to be performed every time 
the scene is loaded, and definitely each time the application is run. 
What if the optimization work is time-consuming? A parametric object 
getting converted into polygons? Hundreds of such conversions? How do 
you save the results of work done by the renderer? Would you rather 
something that involved be done by the application? Is it enough to say 
that, if the application wants to preserve the results of any 
calculations, then it has to do such calculations itself, for the sake 
of consistency and simplicity?
