 destructor

 compute bounding box of the sphere

 Compute normal to closest surface from POINT.

 Compute normal to closest surface from POINT.

 test if point is inside this cone

 Compute distance from inside point to surface of the cone (static)
 Boundary safe algorithm.

 Compute distance from inside point to surface of the cone
 Boundary safe algorithm.

 Compute distance from outside point to surface of the tube
 Boundary safe algorithm.
 compute distance to Z planes

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

 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

 compute closest distance from point px,py to each corner

--- Divide this cone 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.

 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, dZ

 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.

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

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

 create cone mesh points

 create cone mesh points

 Return number of vertices of the mesh representation
