ROOT::Math::PositionVector3D< CoordSystem, Tag > Class Template Reference

### template<class CoordSystem, class Tag = DefaultCoordinateSystemTag> class ROOT::Math::PositionVector3D< CoordSystem, Tag >

Class describing a generic position vector (point) in 3 dimensions.

Class describing a 3D Position vector.

This class is templated on the type of Coordinate system. One example is the XYZPoint which is a vector based on double precision x,y,z data members by using the ROOT::Math::Cartesian3D<double> Coordinate system. The class is having also an extra template parameter, the coordinate system tag, to be able to identify (tag) vector described in different reference coordinate system, like global or local coordinate systems.
