Class Description

 dummy ctor

 Default constructor

 Default constructor

 Default constructor in GEANT3 style
 param[0] = phi1
 param[1] = dphi
 param[2] = nz

 param[3] = z1
 param[4] = Rmin1
 param[5] = Rmax1
 ...

 destructor

 compute bounding box of the pcon

 test if point is inside this shape
 check total z range

 compute closest distance from point px,py to each corner

 compute distance from inside point to surface of the polycone

 compute distance to a pcon Z slice. Segment iz must be valid

 compute distance from outside point to surface of the tube

 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.

 defines z position of a section plane, rmin and rmax at this z.

--- Divide this polycone shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume in case of Z divisions. Z divisions can be
 performed if the divided range is in between two consecutive Z planes.
  In case a wrong division axis is supplied, returns pointer to
 volume that was divided.

 Returns name of axis IAXIS.

 Get range of shape for a given axis.

--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

 print shape parameters

 paint this shape according to option

 paint this shape according to option

 computes next intersection point of curve c with this shape

 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.
---> localize the Z segment

 create polycone mesh points

 create polycone mesh points

 fill size of this 3-D object
