generic class B3x from Bnd (RealType as any)
uses XYZ from gp,
Pnt from gp,
Ax1 from gp,
Ax3 from gp,
Trsf from gp
is
Create returns B3x from Bnd;
---Purpose: Empty constructor.
---C++: inline
Create (theCenter: XYZ from gp; theHSize : XYZ from gp)
returns B3x from Bnd;
---Purpose: Constructor.
---C++: inline
IsVoid (me)
returns Boolean from Standard;
---Purpose: Returns True if the box is void (non-initialized).
---C++: inline
Clear (me:in out);
---Purpose: Reset the box data.
---C++: inline
Add (me:in out; thePnt: XYZ from gp);
---Purpose: Update the box by a point.
Add (me: in out; thePnt: Pnt from gp);
---Purpose: Update the box by a point.
---C++: inline
Add (me:in out; theBox: B3x from Bnd);
---Purpose: Update the box by another box.
---C++: inline
CornerMin (me)
returns XYZ from gp;
---Purpose: Query the lower corner: (Center - HSize). You must make sure that
-- the box is NOT VOID (see IsVoid()), otherwise the method returns
-- irrelevant result.
---C++: inline
CornerMax (me)
returns XYZ from gp;
---Purpose: Query the upper corner: (Center + HSize). You must make sure that
-- the box is NOT VOID (see IsVoid()), otherwise the method returns
-- irrelevant result.
---C++: inline
SquareExtent(me)
returns Real from Standard;
---Purpose: Query the square diagonal. If the box is VOID (see method IsVoid())
-- then a very big real value is returned.
---C++: inline
Enlarge (me:in out; theDiff: Real from Standard);
---Purpose: Extend the Box by the absolute value of theDiff.
---C++: inline
Limit (me:in out; theOtherBox: B3x from Bnd)
returns Boolean from Standard;
---Purpose: Limit the Box by the internals of theOtherBox.
-- Returns True if the limitation takes place, otherwise False
-- indicating that the boxes do not intersect.
Transformed (me; theTrsf: Trsf from gp)
returns B3x from Bnd;
---Purpose: Transform the bounding box with the given transformation.
-- The resulting box will be larger if theTrsf contains rotation.
IsOut (me; thePnt: XYZ from gp)
returns Boolean from Standard;
---Purpose: Check the given point for the inclusion in the Box.
-- Returns True if the point is outside.
---C++: inline
IsOut (me; theCenter : XYZ from gp;
theRadius : Real from Standard;
isSphereHollow: Boolean from Standard = Standard_False)
returns Boolean from Standard;
---Purpose: 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).
IsOut (me; theOtherBox: B3x from Bnd)
returns Boolean from Standard;
---Purpose: Check the given box for the intersection with the current box.
-- Returns True if there is no intersection between boxes.
---C++: inline
IsOut (me; theOtherBox: B3x from Bnd; theTrsf: Trsf from gp)
returns Boolean from Standard;
---Purpose: 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.
IsOut (me; theLine : Ax1 from gp;
isRay : Boolean from Standard = Standard_False;
theOverthickness : Real from Standard = 0.0)
returns Boolean from Standard;
---Purpose: 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'
IsOut (me; thePlane: Ax3 from gp)
returns Boolean from Standard;
---Purpose: Check the given Plane for the intersection with the current box.
-- Returns True if there is no intersection.
IsIn (me; theBox: B3x from Bnd)
returns Boolean from Standard;
---Purpose: Check that the box 'this' is inside the given box 'theBox'. Returns
-- True if 'this' box is fully inside 'theBox'.
---C++: inline
IsIn (me; theBox: B3x from Bnd; theTrsf: Trsf from gp)
returns Boolean from Standard;
---Purpose: 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'.
SetCenter (me: in out; theCenter: XYZ from gp);
---Purpose: Set the Center coordinates
---C++: inline
SetHSize (me: in out; theHSize: XYZ from gp);
---Purpose: Set the HSize (half-diagonal) coordinates.
-- All components of theHSize must be non-negative.
---C++: inline
fields
myCenter : RealType[3] is protected;
myHSize : RealType[3] is protected;
end B3x from Bnd;
