Mesh attachment - Hard constraint joint with no DoF

[Gwenn]

Hi,

I am in the planning phase for a mesh customization system. I have a base object that represent 95% of the outer surface and weight of the final object, and smaller parts that will attach to it.
The base mesh has physics - collision hull, mass, propulsion. It works great.

Now I would like to attach the parts as extensions of the base object. I don't care for their mass or their effect in inertia, etc but I need them to respond to collisions : projectiles, other objects colliding...

So what I need is basically to attach a physical mesh to another, with absolutely no degree of freedom. Is this possible ? Is this a correct way of doing things (I will have a lot of these) ?

Thanks

Basically two ways: combine all the shapes into one compound collision shape or bind them together with solid constraints. The former needs some testing for collisions with parts of the shape. See http://bulletphysics.org/Bullet/phpBB3/ ... php?t=4818 for the latter.
