[PD] gem renders a teapot with 2 heads!

[hard off]

ok, so there is an object in gem called the [teapot] object, which, as
its name suggests, renders a 3-D teapot.

what if i want to render a train, or ultraman, or a bottle of beer, or
a teapot with 2 heads, or something?

are there any objects that would allow me to render something like
that?  i think what would be ideal is if there was some way i could
import a 3-D image made in another program.

is there something like that yet???

also (am i allowed 2 questions in one post?  pleeeease!!!) 

is there a good website where i can get links to ppl involved in the
visual side of PD, or other objects for visual pd use ????  i can find
plenty of stuff about audio, but not so much stuff about GEM and
whatever.

muchos gracias
