 Computes capacity of the shape in [length^3]

 Computes capacity of the shape in [length^3]

 compute bounding box of the tube segment

 Compute normal to closest surface from POINT.

 Compute normal to closest surface from POINT.

 test if point is inside this sphere

 Static method to compute distance to a conical surface with :
 - r1, z1 - radius and Z position of lower base
 - r2, z2 - radius and Z position of upper base
 - phi1, phi2 - phi limits

 compute distance from inside point to surface of the tube segment

 compute distance from inside point to surface of the tube segment

 compute distance from outside point to surface of arbitrary tube

 compute distance from outside point to surface of the tube
 compute safe radius

 compute closest distance from point px,py to each corner

--- Divide this cone segment 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. For Z division
 creates all volumes with different shapes and returns pointer to volume that
 was divided. In case a wrong division axis is supplied, returns pointer to
 volume that was divided.

 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

 in case shape has some negative parameters, these has to be computed
 in order to fit the mother

 print shape parameters

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

 Fill TBuffer3D structure for segments and polygons.

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

 Static method to compute the closest distance from given point to this shape.

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

 Set dimensions of the cone segment.

 Set dimensions of the cone segment from an array.

 Create cone segment mesh points.

 Create cone segment mesh points.

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

 Return number of vertices of the mesh representation

 fill size of this 3-D object
    TVirtualGeoPainter *painter = gGeoManager->GetGeomPainter();
    if (!painter) return;

    Int_t n = gGeoManager->GetNsegments()+1;

    Int_t numPoints = n*4;
    Int_t numSegs   = n*8;
    Int_t numPolys  = n*4-2;
    painter->AddSize3D(numPoints, numSegs, numPolys);

 Fills a static 3D buffer and returns a reference.

 Fills array with n random points located on the line segments of the shape mesh.
 The output array must be provided with a length of minimum 3*npoints. Returns
 true if operation is implemented.
