Class Description

 dummy ctor

 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.

 Divide all range of iaxis in range/step cells

 print shape parameters

 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.

 create polycone mesh points

 create polycone mesh points

 fill size of this 3-D object
