TPGON Class Reference

A polygon.

It has the following parameters:

• name: name of the shape
• title: shape's title
• material: (see TMaterial)
• phi1: the azimuthal angle &phi at which the volume begins (angles are counted counterclockwise)
• dphi1: opening angle of the volume, which extends from phi1 to phi1+dphi
• npdv: number of sides of the cross section between the given phi limits
• nz: number of planes perpendicular to the z axis where the dimension of the section is given – this number should be at least 2
• rmin: array of dimension nz with minimum radius at a given plane
• rmax: array of dimension nz with maximum radius at a given plane
• z: array of dimension nz with z position of given plane
