Detailed Description

Basic 3D Transformation class describing a rotation and then a translation The internal data are a 3D rotation data (represented as a 3x3 matrix) and a 3D vector data.

They are represented and held in this class like a 3x4 matrix (a simple array of 12 numbers).

The class can be constructed from any 3D rotation object (ROOT::Math::Rotation3D, ROOT::Math::AxisAngle, ROOT::Math::Quaternion, etc...) and/or a 3D Vector (ROOT::Math::DislacementVector3D or via ROOT::Math::Translation ) representing a Translation. The Transformation is defined by applying first the rotation and then the translation. A transformation defined by applying first a translation and then a rotation is equivalent to the transformation obtained applying first the rotation and then a translation equivalent to the rotated vector. The operator * can be used to obtain directly such transformations, in addition to combine various transformations. Keep in mind that the operator * (like in the case of rotations ) is not commutative. The operator * is used (in addition to operator() ) to apply a transformations on the vector (DisplacementVector3D and LorentzVector classes) and point (PositionVector3D) classes. In the case of Vector objects the transformation only rotates them and does not translate them. Only Point objects are able to be both rotated and translated.
