ROOT 6.07/09 Reference Guide |
Class describing a 3 dimensional translation.
It can be combined (using the operator *) with the ROOT::Math::Rotation3D classes and ROOT::Math::Transform3D to obtained combined transformations and to operate on points and vectors. Note that a the translation applied to a Vector object (DisplacementVector3D and LorentzVector classes) performes a noop, i.e. it returns the same vector. A translation can be applied only to the Point objects (PositionVector3D classes).
