copy constructor

assignment operator

 destructor

 Computes capacity of the shape in [length^3]

 compute bounding box of the pcon
 Check if the last sections are valid

 Compute normal to closest surface from POINT.

 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

 Defines z position of a section plane, rmin and rmax at this z. Sections
 should be defined in increasing or decreasing Z order and the last section
 HAS to be snum = fNz-1

 Returns number of segments on each mesh circle segment.

--- 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

 Returns Rmin for Z segment IPL.

 Returns Rmax for Z segment IPL.

 Returns Z for segment IPL.

 print shape parameters

 Creates a TBuffer3D describing *this* shape.
 Coordinates are in local reference frame.

 Fill TBuffer3D structure for segments and polygons.

 Compute safety from POINT to segment between planes ipl, ipl+1 within safmin.

 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

 Save a primitive as a C++ statement(s) on output stream "out".

 Set polycone dimensions starting from an array.

 create polycone mesh points

 create polycone mesh points

 Return number of vertices of the mesh representation

 fill size of this 3-D object

    n = gGeoManager->GetNsegments()+1;

    Int_t numPoints = fNz*2*n;
    Int_t numSegs   = 4*(fNz*n-1+(fDphi == 360));
    Int_t numPolys  = 2*(fNz*n-1+(fDphi == 360));
    painter->AddSize3D(numPoints, numSegs, numPolys);

 Returns numbers of vertices, segments and polygons composing the shape mesh.

 Fills a static 3D buffer and returns a reference.
