 gp_Pnt ()
 Creates a point with zero coordinates.

 gp_Pnt (const gp_XYZ &Coord)
 Creates a point from a XYZ object.

 gp_Pnt (const Standard_Real Xp, const Standard_Real Yp, const Standard_Real Zp)
 Creates a point with its 3 cartesian's coordinates : Xp, Yp, Zp.

void SetCoord (const Standard_Integer Index, const Standard_Real Xi)
 Changes the coordinate of range Index :
Index = 1 => X is modified
Index = 2 => Y is modified
Index = 3 => Z is modified
//! Raised if Index != {1, 2, 3}.

void SetCoord (const Standard_Real Xp, const Standard_Real Yp, const Standard_Real Zp)
 For this point, assigns the values Xp, Yp and Zp to its three coordinates.

void SetX (const Standard_Real X)
 Assigns the given value to the X coordinate of this point.

void SetY (const Standard_Real Y)
 Assigns the given value to the Y coordinate of this point.

void SetZ (const Standard_Real Z)
 Assigns the given value to the Z coordinate of this point.

void SetXYZ (const gp_XYZ &Coord)
 Assigns the three coordinates of Coord to this point.

Standard_Real Coord (const Standard_Integer Index) const
 Returns the coordinate of corresponding to the value of Index :
Index = 1 => X is returned
Index = 2 => Y is returned
Index = 3 => Z is returned
Raises OutOfRange if Index != {1, 2, 3}.
//! Raised if Index != {1, 2, 3}.

void Coord (Standard_Real &Xp, Standard_Real &Yp, Standard_Real &Zp) const
 For this point gives its three coordinates Xp, Yp and Zp.

Standard_Real X () const
 For this point, returns its X coordinate.

Standard_Real Y () const
 For this point, returns its Y coordinate.

Standard_Real Z () const
 For this point, returns its Z coordinate.

const gp_XYZXYZ () const
 For this point, returns its three coordinates as a XYZ object.

const gp_XYZCoord () const
 For this point, returns its three coordinates as a XYZ object.

gp_XYZChangeCoord ()
 Returns the coordinates of this point.
Note: This syntax allows direct modification of the returned value.

void BaryCenter (const Standard_Real Alpha, const gp_Pnt &P, const Standard_Real Beta)
 Assigns the result of the following expression to this point
(Alpha*this + Beta*P) / (Alpha + Beta)

Standard_Boolean IsEqual (const gp_Pnt &Other, const Standard_Real LinearTolerance) const
 Comparison
Returns True if the distance between the two points is
lower or equal to LinearTolerance.

Standard_Real Distance (const gp_Pnt &Other) const
 Computes the distance between two points.

Standard_Real SquareDistance (const gp_Pnt &Other) const
 Computes the square distance between two points.

void Mirror (const gp_Pnt &P)
 Performs the symmetrical transformation of a point
with respect to the point P which is the center of
the symmetry.

gp_Pnt Mirrored (const gp_Pnt &P) const
 Performs the symmetrical transformation of a point
with respect to an axis placement which is the axis
of the symmetry.

void Mirror (const gp_Ax1 &A1)
gp_Pnt Mirrored (const gp_Ax1 &A1) const
 Performs the symmetrical transformation of a point
with respect to a plane. The axis placement A2 locates
the plane of the symmetry : (Location, XDirection, YDirection).

void Mirror (const gp_Ax2 &A2)
gp_Pnt Mirrored (const gp_Ax2 &A2) const
 Rotates a point. A1 is the axis of the rotation.
Ang is the angular value of the rotation in radians.

void Rotate (const gp_Ax1 &A1, const Standard_Real Ang)
gp_Pnt Rotated (const gp_Ax1 &A1, const Standard_Real Ang) const
 Scales a point. S is the scaling value.

void Scale (const gp_Pnt &P, const Standard_Real S)
gp_Pnt Scaled (const gp_Pnt &P, const Standard_Real S) const
 Transforms a point with the transformation T.

void Transform (const gp_Trsf &T)
gp_Pnt Transformed (const gp_Trsf &T) const
 Translates a point in the direction of the vector V.
The magnitude of the translation is the vector's magnitude.

void Translate (const gp_Vec &V)
gp_Pnt Translated (const gp_Vec &V) const
 Translates a point from the point P1 to the point P2.

void Translate (const gp_Pnt &P1, const gp_Pnt &P2)
gp_Pnt Translated (const gp_Pnt &P1, const gp_Pnt &P2) const
const gp_XYZ_CSFDB_Getgp_Pntcoord () const
