DESCRIPTION
     3D box which has planes parallel to the major axes and is specified by
     two points on a diagonal. This class is part of the standard Inventor
     datatype classes and is used as input and output to geometry operations
     (see SoGetBoundingBoxAction).

METHODS
                         SbBox3f()
                         SbBox3f(float xmin, float ymin, float zmin float
                              xmax, float ymax, float zmax)
                         SbBox3f(const SbVec3f &min, const SbVec3f &max)
     void                ~SbBox3f()
          Constructors and destructor for a 3D float box. xmin, ymin, zmin,
          xmax, ymax and zmax are the bounds of the box. min and max are the
          corners of the diagonal that define the box.

     const SbVec3f &     getMin()
     const SbVec3f &     getMax()
          Returns the minimum and maximum points of the box. The minimum point
          is the corner of the box with the lowest X, Y, and Z values. The
          maximum point is the corner of the box with the highest X, Y, and Z
          values.

     SbVec3f             getCenter()
          Returns the center of the box.

     void                extendBy(const SbVec3f &point)
     void                extendBy(const SbBox3f &box)
          Extends this box (if necessary) to contain the specified point or
          other box.

     SbBool              intersect(const SbVec3f &point)
     SbBool              intersect(const SbBox3f &box)
          Returns TRUE if the specified point or box intersects this box.

     void                setBounds(float xmin, float ymin, float zmin, float
                              xmax, float ymax, float zmax)
     void                setBounds(const SbVec3f &min, const SbVec3f &max)
          Sets the corners of the box.

     void                getBounds(float &xmin, float &ymin, float &zmin,
                              float &xmax, float &ymax, float &zmax)
     void                getBounds(SbVec3f &min, SbVec3f &max)
          Gets the corners of the box.

     void                getOrigin(float &x0, float &y0, float &z0)
          Gets box origin which is the same as the minimum corner of the box.

     void                getSize(float &x, float &y, float &z)
          Gets box size.

     void                makeEmpty()
          Makes an empty box.

     SbBool              isEmpty()
          Returns TRUE if the box is empty, and FALSE otherwise.

     SbBool              hasVolume()
          Returns TRUE if all three dimensions of the box have positive size,
          and FALSE otherwise.

     void                getSpan(SbVec3f &dir, float &dMin, float &dMax)
          Finds the span of a box along a specified direction. The span is the
          total distance the box occupies along a given direction. The total
          distance is returned in the form of a minimum and maximum distance
          from the origin of each of the corners of the box along the given
          direction. The difference between these two values is the span.

     void                transform(const SbMatrix &mx)
          Transforms box by matrix, enlarging box to contain result.

     float               getVolume()
          Returns the volume of the box.
