Well, this is not the objects, but the rendering in the IDL object
graphics routines. At RSI they apparently have the idea that no later
than 2 years from now everyone will 
sit in front of a machine with a sophisticated 3D rendering engine
(and that all the Linuxes will by then support 3D rendering natively
;-). May still be that direct graphics is a little faster for certain
applications. I'd dare to postulate the following theorem:
   the more you care about individual pixels or line fragments, the
directer your graphics should be.
