[ODE] Holes

[naspiri]

My first mail to this list, glad to be here :-)... My english isn't so 
well, I only hope it's understandable...
I'm a newbie, using ODE in a pool game, I made a demo with balls rolling 
and colliding on a table,
but now I would introduce the holes... How can I make that? How can I 
create a hole on a plane with ODE?
I think there are different ways and one is trimesh I suppose... is it 
the only option?
