Class Description

 Default constructor

 Constructor

 Constructor

 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

 decide 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 - already computed in this case

 test if point is inside this shape

 compute distance from inside point to surface of the box

 compute distance from outside point to surface of the box

 computes the distance to next surface of the box along a ray
 starting from given point to the given direction.

 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

 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

 print shape parameters

 computes next intersection point of curve c with this shape

 paint this shape according to option

 paint this shape according to option

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

 set parameters of box

 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

 create box points

 create box points

 fill size of this 3-D object
