I didn't know of the existence of this program. Sounds very interesting.

Sure. In fact, that's the reason why the Maxima-Vtk interface was
initiated.
It shouldn't be too difficult to draw arbitrary surfaces based on
triangles, parallelograms or polyhedral angles, like in
http://riotorto.users.sourceforge.net/vtk/poly
Or build a new graphic object for this sort of tasks.
Vtk is extensively used in medical and remote sensing imagery and it has
stl writer and reader classes.
