class ROOT::Math::Translation3D


    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).

Function documentation

Translation3D()

       Default constructor ( zero translation )

{}

Translation3D(IT begin, IT end)

      Construct given a pair of pointers or iterators defining the
      beginning and end of an array of 3 Scalars representing the z,y,z of the translation vector

Translation3D(double dx, double dy, double dz)

      Construct from x,y,z values representing the translation

{ }

void SetComponents(IT begin, IT end)

      Set the 3  components given an iterator to the start of
      the desired data, and another to the end (3 past start).

void GetComponents(IT begin, IT end)

      Get the 3  components into data specified by an iterator begin
      and another to the end of the desired data (12 past start).

SetXYZ(double dx, double dy, double dz)

      Set the XYZ vector components from 3 scalars

PositionVector3D<CoordSystem,Tag> operator()(const PositionVector3D <CoordSystem,Tag> & p)

 operations on points and vectors

      Transformation operation for Position Vector in any coordinate system and default tag

void Invert()

       Invert the transformation in place

Translation3D Inverse() const

      Return the inverse of the transformation.
