	Bnd_B3d ()
	Empty constructor.

	Bnd_B3d (const gp_XYZ &theCenter, const gp_XYZ &theHSize)
	Constructor.

Standard_Boolean	IsVoid () const
	Returns True if the box is void (non-initialized).

void	Clear ()
	Reset the box data.

void	Add (const gp_XYZ &thePnt)
	Update the box by a point.

void	Add (const gp_Pnt &thePnt)
	Update the box by a point.

void	Add (const Bnd_B3d &theBox)
	Update the box by another box.

gp_XYZ	CornerMin () const
	Query the lower corner: (Center - HSize). You must make sure that the box is NOT VOID (see IsVoid()), otherwise the method returns irrelevant result.

gp_XYZ	CornerMax () const
	Query the upper corner: (Center + HSize). You must make sure that the box is NOT VOID (see IsVoid()), otherwise the method returns irrelevant result.

Standard_Real	SquareExtent () const
	Query the square diagonal. If the box is VOID (see method IsVoid()) then a very big real value is returned.

void	Enlarge (const Standard_Real theDiff)
	Extend the Box by the absolute value of theDiff.

Standard_Boolean	Limit (const Bnd_B3d &theOtherBox)
	Limit the Box by the internals of theOtherBox. Returns True if the limitation takes place, otherwise False indicating that the boxes do not intersect.

Bnd_B3d	Transformed (const gp_Trsf &theTrsf) const
	Transform the bounding box with the given transformation. The resulting box will be larger if theTrsf contains rotation.

Standard_Boolean	IsOut (const gp_XYZ &thePnt) const
	Check the given point for the inclusion in the Box. Returns True if the point is outside.

Standard_Boolean	IsOut (const gp_XYZ &theCenter, const Standard_Real theRadius, const Standard_Boolean isSphereHollow=Standard_False) const
	Check a sphere for the intersection with the current box. Returns True if there is no intersection between boxes. If the parameter 'IsSphereHollow' is True, then the intersection is not reported for a box that is completely inside the sphere (otherwise this method would report an intersection).

Standard_Boolean	IsOut (const Bnd_B3d &theOtherBox) const
	Check the given box for the intersection with the current box. Returns True if there is no intersection between boxes.

Standard_Boolean	IsOut (const Bnd_B3d &theOtherBox, const gp_Trsf &theTrsf) const
	Check the given box oriented by the given transformation for the intersection with the current box. Returns True if there is no intersection between boxes.

Standard_Boolean	IsOut (const gp_Ax1 &theLine, const Standard_Boolean isRay=Standard_False, const Standard_Real theOverthickness=0.0) const
	Check the given Line for the intersection with the current box. Returns True if there is no intersection. isRay==True means intersection check with the positive half-line theOverthickness is the addition to the size of the current box (may be negative). If positive, it can be treated as the thickness of the line 'theLine' or the radius of the cylinder along 'theLine'.

Standard_Boolean	IsOut (const gp_Ax3 &thePlane) const
	Check the given Plane for the intersection with the current box. Returns True if there is no intersection.

Standard_Boolean	IsIn (const Bnd_B3d &theBox) const
	Check that the box 'this' is inside the given box 'theBox'. Returns True if 'this' box is fully inside 'theBox'.

Standard_Boolean	IsIn (const Bnd_B3d &theBox, const gp_Trsf &theTrsf) const
	Check that the box 'this' is inside the given box 'theBox' transformed by 'theTrsf'. Returns True if 'this' box is fully inside the transformed 'theBox'.

void	SetCenter (const gp_XYZ &theCenter)
	Set the Center coordinates.

void	SetHSize (const gp_XYZ &theHSize)
	Set the HSize (half-diagonal) coordinates. All components of theHSize must be non-negative.
