How to update collisionshape of the body

Hi,
Can any one tell me is there anyway to update the collision shape of the body on the fly, when I tried calculating the collision shape for a scenenode in frame listener the application crashes, so is there any other way to do this..?

thank you in advance

none that I know of..

You can create new collision bodies, remove the previous one and attach the new one to your body inside the frame listener.. I've not tried it but I'm damn sure it'll bring the system on it's knees..

you can try this

OgreNewt::Collision* col = new OgreNewt::CollisionPrimitives::Ellipsoid(blah blah);
newtBody->setCollision( col );
