Class Description

 TGeoTube - cylindrical tube class. It takes 3 parameters :
            inner radius, outer radius and half-length dz.

_____________________________________________________________________________
 TGeoTubeSeg - a phi segment of a tube. Has 5 parameters :
            - the same 3 as a tube;
            - first phi limit (in degrees)
            - second phi limit

_____________________________________________________________________________
 TGeoCtub - a tube segment cut with 2 planes. Has 11 parameters :
            - the same 5 as a tube segment;
            - x, y, z components of the normal to the -dZ cut plane in
              point (0, 0, -dZ);
            - x, y, z components of the normal to the +dZ cut plane in
              point (0, 0, dZ);

 destructor

 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 tube segment
 first check if point is inside the tube

 compute closest distance from point px,py to each corner

 Compute distance from inside point to surface of the tube segment (static)
 Boundary safe algorithm.
 Do Z

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

 Static method to compute distance to arbitrary tube segment from outside point
 Boundary safe algorithm.

 compute distance from outside point to surface of the tube segment
 fist localize point w.r.t tube

--- Divide this tube 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 radialdivision
 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".

 create sphere mesh points

 create sphere mesh points

 Return number of vertices of the mesh representation
