class TGeoBBox: public TGeoShape

 Default constructor

 Constructor where half-lengths are provided.

 Constructor with shape name.

 Constructor based on the array of parameters
 param[0] - half-length in x
 param[1] - half-length in y
 param[2] - half-length in z

 Destructor

 Check if 2 positioned boxes overlap.

 Computes capacity of the shape in [length^3].

 Computes normal to closest surface from POINT.

 Decides fast if the bounding box could be crossed by a vector.

 Compute closest distance from point px,py to each corner.

--- Divide this box shape belonging to volume "voldiv" into ndiv equal volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume. In case a wrong division axis is supplied,
 returns pointer to volume to be divided.

 Compute bounding box - nothing to do in this case.

 Test if point is inside this shape.

 Static method to check if point[3] is located inside a box of having dx, dy, dz
 as half-lengths.

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

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

 Compute distance from outside point to surface of the box.
 Boundary safe algorithm.

 Compute distance from outside point to surface of the box.
 Boundary safe algorithm.

 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

 Get area in internal units of the facet with a given index.
 Possible index values:
    0 - all facets togeather
    1 to 6 - facet index from bottom to top Z

 Fills array with n random points located on the surface of indexed facet.
 The output array must be provided with a length of minimum 3*npoints. Returns
 true if operation succeeded.
 Possible index values:
    0 - all facets togeather
    1 to 6 - facet index from bottom to top Z

 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.

 Fills real parameters of a positioned box inside this one. Returns 0 if successfull.

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

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

 Prints shape parameters

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

 Fills TBuffer3D structure for segments and polygons.

 Computes the closest distance from given point to this shape.

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

 Set parameters of the box.

 Set dimensions based on the array of parameters
 param[0] - half-length in x
 param[1] - half-length in y
 param[2] - half-length in z

 Fill box vertices to an array.

 Fill box points.

 Fill box points.

 fill size of this 3-D object
    TVirtualGeoPainter *painter = gGeoManager->GetGeomPainter();
    if (painter) painter->AddSize3D(8, 12, 6);

 Fills a static 3D buffer and returns a reference.

 Fills the supplied buffer, with sections in desired frame
 See TBuffer3D.h for explanation of sections, frame etc.

 Check the inside status for each of the points in the array.
 Input: Array of point coordinates + vector size
 Output: Array of Booleans for the inside of each point

 Compute the normal for an array o points so that norm.dot.dir is positive
 Input: Arrays of point coordinates and directions + vector size
 Output: Array of normal directions

 Compute distance from array of input points having directions specisied by dirs. Store output in dists

 Compute distance from array of input points having directions specisied by dirs. Store output in dists

 Compute safe distance from each of the points in the input array.
 Input: Array of point coordinates, array of statuses for these points, size of the arrays
 Output: Safety values
