Class Description


PCON is a polycone. 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) - dphi opening angle of the volume, which extends from phi1 to phi1+dphi - 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
