[ODE] Mass translation problems

[Jon Watte]

The translation of a mass is not respected by a body. The center of mass is always at the center of the body. You have to instead translate your geom, typically using a GeomTransform. This is mentioned in the FAQ, by the way.

Hi,

I have a dynamic trimesh (with a box mass) attached with a hinge joint 
to the world. I'm trying displace the centre of mass of this rigid body 
using dMassTranslate, but I can't seem to get it to work. The effect I 
want from this is a kind of pendulum thingy.

I think I have read something about this function not working properly 
on this list a while back. Has anybody got this function to work? Any 
ideas of how to accomplish this?

cheers
