class TGeoEltu: public TGeoTube

 Dummy constructor

 Default constructor specifying X and Y semiaxis length

 Default constructor specifying X and Y semiaxis length

 Default constructor specifying minimum and maximum radius
 param[0] =  A
 param[1] =  B
 param[2] = dz

 destructor

 Computes capacity of the shape in [length^3]

 compute bounding box of the tube

 Compute normal to closest surface from POINT.

 test if point is inside the elliptical tube

 compute closest distance from point px,py to each vertex

 compute distance from inside point to surface of the tube

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

 Divide the shape along one 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

 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".

 Set dimensions of the eliptical tube.

 Set shape dimensions starting from an array.

 Create eliptical tube mesh points

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

 Returns the number of vertices on the mesh.

 Create eliptical tube mesh points

 Fills a static 3D buffer and returns a reference.
