成员函数说明

◆ BaryCenter()

void GPnt.BaryCenter	(	double	theAlpha,
		GPnt	theP,
		double	theBeta
	)

Assigns the result of the following expression to this point (theAlpha*this + theBeta*theP) / (theAlpha + theBeta)

◆ ChangeCoord()

GXYZ GPnt.ChangeCoord ( )

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

◆ Coord() [1/3]

GXYZ GPnt.Coord ( )

For this point, returns its three coordinates as a XYZ object.

◆ Coord() [2/3]

void GPnt.Coord	(	double[]	theXp,
		double[]	theYp,
		double[]	theZp
	)

For this point gives its three coordinates theXp, theYp and theZp.

◆ Coord() [3/3]

double GPnt.Coord ( int theIndex )

Returns the coordinate of corresponding to the value of theIndex : theIndex = 1 => X is returned theIndex = 2 => Y is returned theIndex = 3 => Z is returned Raises OutOfRange if theIndex != {1, 2, 3}. Raised if theIndex != {1, 2, 3}.

◆ Distance()

double GPnt.Distance ( GPnt theOther )

Computes the distance between two points.

◆ IsEqual()

boolean GPnt.IsEqual	(	GPnt	theOther,
		double	theLinearTolerance
	)

Comparison Returns True if the distance between the two points is lower or equal to theLinearTolerance.

◆ Mirror()

void GPnt.Mirror ( GPnt theP )

Performs the symmetrical transformation of a point with respect to the point theP which is the center of the symmetry.

◆ Mirrored() [1/3]

GPnt GPnt.Mirrored ( GAx1 theA1 )

Performs the symmetrical transformation of a point with respect to a plane. The axis placement theA2 locates the plane of the symmetry : (Location, XDirection, YDirection).

◆ Mirrored() [2/3]

GPnt GPnt.Mirrored ( GAx2 theA2 )

Rotates a point. theA1 is the axis of the rotation. theAng is the angular value of the rotation in radians.

◆ Mirrored() [3/3]

GPnt GPnt.Mirrored ( GPnt theP )

Performs the symmetrical transformation of a point with respect to an axis placement which is the axis of the symmetry.

◆ Scale()

void GPnt.Scale	(	GPnt	theP,
		double	theS
	)

Scales a point. theS is the scaling value.

◆ SetCoord() [1/2]

void GPnt.SetCoord	(	double	theXp,
		double	theYp,
		double	theZp
	)

For this point, assigns the values theXp, theYp and theZp to its three coordinates.

◆ SetCoord() [2/2]

void GPnt.SetCoord	(	int	theIndex,
		double	theXi
	)

Changes the coordinate of range theIndex : theIndex = 1 => X is modified theIndex = 2 => Y is modified theIndex = 3 => Z is modified Raised if theIndex != {1, 2, 3}.

◆ SetX()

void GPnt.SetX ( double theX )

Assigns the given value to the X coordinate of this point.

◆ SetXYZ()

void GPnt.SetXYZ ( GXYZ theCoord )
