If you just try to convert the point from global to local coordinates, use
localPt=state->ori.Conjugate()*(pt-state.pos) > localP1 = state1.ori.Conjugate() * tempP1 * state1.ori; I think mathematitians write this multiplication from both sides, but they really mean just rotation by the inverse (=conjugate, for normalized) quaternion. v _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
