Its actually not that big, and it's useful for things other than 3d.
Interpolation could be used for things like gradient colour fills for 
plot backgrunds or bars in barplots, drawing light spectra, etc.

I've much about with some of this using existing primitives, and its 
quite hard work to get the effects I want.
