class TGeoSphere: public TGeoBBox

 Default constructor

 Default constructor specifying minimum and maximum radius

 Default constructor specifying minimum and maximum radius

 Default constructor specifying minimum and maximum radius
 param[0] = Rmin
 param[1] = Rmax

 destructor

 Computes capacity of the shape in [length^3]

 compute bounding box of the sphere
   Double_t xmin, xmax, ymin, ymax, zmin, zmax;

 Compute normal to closest surface from POINT.

 Check if a point in local sphere coordinates is close to a boundary within
 shape tolerance. Return values:
   0 - not close to boundary
   1 - close to Rmin boundary
   2 - close to Rmax boundary
   3,4 - close to phi1/phi2 boundary
   5,6 - close to theta1/theta2 boundary

 Check if a point is inside radius/theta/phi ranges for the spherical sector.

 test if point is inside this sphere
 check Rmin<=R<=Rmax

 compute closest distance from point px,py to each corner

 compute distance from outside point to surface of the sphere
 Check if the bounding box is crossed within the requested distance

 compute distance from inside point to surface of the sphere

 compute distance to sphere of radius rsph. Direction has to be a unit vector

 Divide all range of iaxis in range/step cells

 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

 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.

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

 Set spherical segment dimensions.

 Set dimensions of the spherical segment starting from a list of parameters.

 Set the number of divisions of mesh circles keeping aspect ratio.

 create sphere mesh points

 create sphere mesh points

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

 Return number of vertices of the mesh representation

 obsolete - to be removed

 Fills a static 3D buffer and returns a reference.
