29It has the following parameters:
30
31 - name: name of the shape
32 - title: shape's title
33 - material: (see TMaterial)
34 - phi1: the azimuthal angle phi at which the volume begins (angles
35 are counted counterclockwise)
36 - dphi: opening angle of the volume, which extends from
37 phi1 to phi1+dphi
38 - nz: number of planes perpendicular to the z axis where
39 the dimension of the section is given -- this number
40 should be at least 2
41 - rmin: array of dimension nz with minimum radius at a given plane
42 - rmax: array of dimension nz with maximum radius at a given plane
43 - z: array of dimension nz with z position of given plane
