Standard_EXPORT | Bnd_Box () |
Creates an empty Box. The constructed box is qualified Void. Its gap is null. . | |
Standard_EXPORT void | SetWhole () |
Sets this bounding box so that it covers the whole of 3D space. It is infinitely long in all directions. . | |
Standard_EXPORT void | SetVoid () |
Sets this bounding box so that it is empty. All points are outside a void box. . | |
Standard_EXPORT void | Set (const gp_Pnt &P) |
Sets this bounding box so that it bounds - the point P. This involves first setting this bounding box to be void and then adding the point P. . | |
Standard_EXPORT void | Set (const gp_Pnt &P, const gp_Dir &D) |
Sets this bounding box so that it bounds the half-line defined by point P and direction D, i.e. all points M defined by M=P+u*D, where u is greater than or equal to 0, are inside the bounding volume. This involves first setting this box to be void and then adding the half-line. . | |
Standard_EXPORT void | Update (const Standard_Real aXmin, const Standard_Real aYmin, const Standard_Real aZmin, const Standard_Real aXmax, const Standard_Real aYmax, const Standard_Real aZmax) |
Enlarges this bounding box, if required, so that it contains at least: - interval [ aXmin,aXmax ] in the "X Direction", - interval [ aYmin,aYmax ] in the "Y Direction", - interval [ aZmin,aZmax ] in the "Z Direction"; . | |
Standard_EXPORT void | Update (const Standard_Real X, const Standard_Real Y, const Standard_Real Z) |
Adds a point of coordinates (X,Y,Z) to this bounding box. . | |
Standard_EXPORT Standard_Real | GetGap () const |
Returns the gap of this bounding box. . | |
Standard_EXPORT void | SetGap (const Standard_Real Tol) |
Set the gap of this bounding box to abs(Tol). . | |
Standard_EXPORT void | Enlarge (const Standard_Real Tol) |
Enlarges the box with a tolerance value. (minvalues-Abs(<tol>) and maxvalues+Abs(<tol>)) This means that the minimum values of its X, Y and Z intervals of definition, when they are finite, are reduced by the absolute value of Tol, while the maximum values are increased by the same amount. . | |
Standard_EXPORT void | Get (Standard_Real &aXmin, Standard_Real &aYmin, Standard_Real &aZmin, Standard_Real &aXmax, Standard_Real &aYmax, Standard_Real &aZmax) const |
Returns the bounds of this bounding box. The gap is included. If this bounding box is infinite (i.e. "open"), returned values may be equal to +/- Precision::Infinite(). if IsVoid() . | |
Standard_EXPORT void | OpenXmin () |
The Box will be infinitely long in the Xmin direction. . | |
Standard_EXPORT void | OpenXmax () |
The Box will be infinitely long in the Xmax direction. . | |
Standard_EXPORT void | OpenYmin () |
The Box will be infinitely long in the Ymin direction. . | |
Standard_EXPORT void | OpenYmax () |
The Box will be infinitely long in the Ymax direction. . | |
Standard_EXPORT void | OpenZmin () |
The Box will be infinitely long in the Zmin direction. . | |
Standard_EXPORT void | OpenZmax () |
The Box will be infinitely long in the Zmax direction. . | |
Standard_EXPORT Standard_Boolean | IsOpenXmin () const |
Returns true if this bounding box is open in the Xmin direction. . | |
Standard_EXPORT Standard_Boolean | IsOpenXmax () const |
Returns true if this bounding box is open in the Xmax direction. . | |

Returns true if this bounding box is open in the Zmin direction. . | |
Standard_EXPORT Standard_Boolean | IsOpenZmax () const |
Returns true if this bounding box is open in the Zmax direction. . | |
Standard_EXPORT Standard_Boolean | IsWhole () const |
Returns true if this bounding box is infinite in all 6 directions (WholeSpace flag). . | |
Standard_EXPORT Standard_Boolean | IsVoid () const |
Returns true if this bounding box is empty (Void flag). . | |
Standard_EXPORT Standard_Boolean | IsXThin (const Standard_Real tol) const |
true if xmax-xmin < tol. | |
Standard_EXPORT Standard_Boolean | IsYThin (const Standard_Real tol) const |
true if ymax-ymin < tol. | |
Standard_EXPORT Standard_Boolean | IsZThin (const Standard_Real tol) const |
true if zmax-zmin < tol. | |
Standard_EXPORT Standard_Boolean | IsThin (const Standard_Real tol) const |
Returns true if IsXThin, IsYThin and IsZThin are all true, i.e. if the box is thin in all three dimensions. . | |
Standard_EXPORT Bnd_Box | Transformed (const gp_Trsf &T) const |
Returns a bounding box which is the result of applying the transformation T to this bounding box. Warning Applying a geometric transformation (for example, a rotation) to a bounding box generally increases its dimensions. This is not optimal for algorithms which use it. . | |
Standard_EXPORT void | Add (const Bnd_Box &Other) |
Adds the box <other> to <me>. . | |
Standard_EXPORT void | Add (const gp_Pnt &P) |
Adds a Pnt to the box. . | |
Standard_EXPORT void | Add (const gp_Pnt &P, const gp_Dir &D) |
Extends <me> from the Pnt | |
Standard_EXPORT void | Add (const gp_Dir &D) |
Extends the Box in the given Direction, i.e. adds an half-line. The box may become infinite in 1,2 or 3 directions. . | |
Standard_EXPORT Standard_Boolean | IsOut (const gp_Pnt &P) const |
Returns True if the Pnt is out the box. . | |
