I test in Demo05_SimpleVehicle and I think make the "ellipsoid.mesh" in Demo05_SimpleVehicle to be seem
more spring and it is football.



Ogre::Vector3 dir, vec;

			Ogre::Quaternion camorient = msnCam->getWorldOrientation();

			vec = Ogre::Vector3(0,0,-1);



			dir = camorient * vec;



			Entity* ent;

			SceneNode* node;

			Ogre::String name;

			Ogre::Vector3 pos = msnCam->getWorldPosition();



			name = "Body "+Ogre::StringConverter::toString( count++ );



			ent = mSceneMgr->createEntity( name, "ellipsoid.mesh" );

			node = mSceneMgr->getRootSceneNode()->createChildSceneNode( name );

			node->attachObject( ent );



			ent->setMaterialName( "Simple/dirt01" );



			OgreNewt::Collision* col = new OgreNewt::CollisionPrimitives::Ellipsoid( m_World, Ogre::Vector3(1,1,1) );

			OgreNewt::Body* body = new OgreNewt::Body( m_World, col );



			Ogre::Vector3 inertia = OgreNewt::MomentOfInertia::CalcSphereSolid( 2.0, 0.1 );

			body->setMassMatrix( 2.0, inertia );

			body->attachToNode( node );

			body->setStandardForceCallback();

			body->setPositionOrientation( pos, camorient );

			body->setVelocity( (dir * 50.0) );

Can you help me?
look forword...

walaber:
I view your materials and collision in past newton "NDB_v130demos" example.
the ball in materials and collision is enough spring and is like football.
But the "ellipsoid.mesh"'s ball is'n enough spring in the Demo05_SimpleVehicle.
How to do the "ellipsoid.mesh"'s ball in the Demo05_SimpleVehicle the same as materials and collision in past newton "NDB_v130demos" example?

Looking earnest forword to your help...

you need to create material objects, then create a MaterialPair, and set the default elasticity and softness for that material pair.

afterwards, don't forget to assign the proper materials to the rigid bodies.

have a look at the material demo w/ OgreNewt to see how to create materials.
