Are you sure I can use this as a 3D physics engine for my game ? I's a 
data analysis framework. Or maybe I misunderstood the purpose of this 
soft.

Create a wrapper is really not something I use to. I looked at a bit, 
but it's not my cup of tea.

Thank you for your help, but I have to decline.

My first attempt to create a 3D physics engine was just a modified 2D 
engine. Because I don't need rotations, I think I can fulfill by myself 
what I'm looking for.


I will not try to create a "real" 3D engine, rather something pretty 
simple. I looked at your code, and I'm looking at Chipmunk's code to see 
how things (shape, body, vector) are working.

The actual version of my code is working, but there is a lot of work to 
do.
