[ODE] Modeling a room (or how to do an inverted cube rigid body inode)

[Jon Watte]

Build a trimesh with the triangle normals pointing inwards.

Hello,
I'm wondering how to do a simple rigid body that fits in a room. I mean,
having a simple room with a simple texture with a cubic shape. Now my
modelers have put some objects in it, let's say spheres and boxes.
For what i've seen i can't simply pass the room BB to ODE and expect
that the objects inside the room effectively collide with the room walls
(as the BB normals point outside the room).
So, is there a way to say "yeah, build a box but the normals point
inside". I suppose there's an easy one: "build the planes". If that's
the only way, well, i will have to do it that way :)

Thanx in advance,

Toni
