[Pyode-user] interpenetration and bouncing

[Lionel b. De N. <lio...@fr...>]

Hello all,
I face a strange problem using pyODE.
[ I am quite new with this engine, but I think I have done my homework 
and read the doc carefully.
So I hope i won't add Noise in the mailing list.]

Mainly, the objects are inter penetrating. I have read the faq 
(especially this section 
http://www.ode.org/ode-latest-userguide.html#sec_12_3_0 ) but I am quite 
surprised of the low quality of the result I get (i.e the deepness of 
interpenetration). I have few object, all of them are axis aligned 
boxes. Collision Detection and response should be quite simple, at least 
much simpler than with complex meshes.

You can look the script at this address : http://pastebin.com/605773

I have set up a group of cubes with a initial linear velocity and let 
the glide and bounce inside a room (simulated by a list of GeomPlane).

This simulation is supposed to be 2D, so I constrained the cubes with a 
very low ceiling (slightly higher than they are) and I reset their Z 
coord (position; speed, rotation) to their original value. I had to do 
this because, if not, the cubes would go upward or downward after a 
collision (???).

Frankly, I am quite puzzled by the whole thing. So if a generous soul 
wants to help, any input is welcome.
