template<class T>
class ROOT::Math::CylindricalEta3D< T >

Class describing a cylindrical coordinate system based on eta (pseudorapidity) instead of z.

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

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