[Q] Alice / Wonderland models and performance?

Hi all,
I'm writing up a little simulator lately, and would like to have it
representable and maybe controllable within a 3d interface. To that end,
what's the most direct way to get a basic human form into Alice? I've
been told that the original Alice project's file format has changed
since the Squeak port, and I haven't used Squeak's 3D capabilities at
all aside from toying with Squeak's single demo. My hope is that there's
already one available, of course, that fits Squeak's input format. I
don't need anything fancy, atm, just something with articulated limbs
and such (the old-school method of rendering each part with a polyhedron
comes to mind ;).
Now, I've working on video game graphics engine design and optimization
before, even for model formats, and a cursory look at Alice and
Wonderland indicates that it does all of its scene-culling using
polygon-analysis alone, instead of including logic for, say, convex
hulls and their analyses. This suggests that it doesn't really scale
well unless I layer some logic over it to avoid a scene-rendering where
it has to sort millions of polygons for each frame. I'd like to include
some good logic for convex hulls, but to be honest I don't know where to
begin. What can you tell me?
TIA
