Data Members

    protected:

      Double_t fDX         X half-length
      Double_t fDY         Y half-length
      Double_t fDZ         Z half-length
      Double_t fOrigin[3]  box origin

 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.

 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.

 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

 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.
