class ROOT::Math::Plane3D

renormalize a,b,c to unit

 normalize the plane

default constructor create plane z = 0

generic constructors from the four scalar values describing the plane
according to the equation ax + by + cz + d = 0
\param a scalar value
\param b scalar value
\param c scalar value
\param d sxcalar value

constructor a Plane3D from a normal vector and a point coplanar to the plane
\param n normal expressed as a ROOT::Math::DisplacementVector3D<Cartesian3D<double> >
\param p point  expressed as a  ROOT::Math::PositionVector3D<Cartesian3D<double> >

 compiler-generated copy ctor and dtor are fine.
 ------ assignment ------

Assignment operator from other Plane3D class

Return the a coefficient of the plane equation \f$ a*x + b*y + c*z + d = 0 \f$. It is also the
x-component of the vector perpendicular to the plane.

Return the b coefficient of the plane equation \f$ a*x + b*y + c*z + d = 0 \f$. It is also the
y-component of the vector perpendicular to the plane

Return the c coefficient of the plane equation \f$ a*x + b*y + c*z + d = 0 \f$. It is also the
z-component of the vector perpendicular to the plane

Return normal vector to the plane as Cartesian DisplacementVector

Return the Hesse Distance (distance from the origin) of the plane or
the d coefficient expressed in normalize form
