template<class T>
class ROOT::Math::Cylindrical3D< T >

Class describing a cylindrical coordinate system based on rho, z and phi.

Class describing a 3D Cylindrical Eta coordinate system (rho, z, phi coordinates)

The base coordinates are rho (transverse component) , z and phi Phi is restricted to be in the range [-PI,PI)
