Public 成员函数
	GDir (global::System.IntPtr cPtr, bool cMemoryOwn)
	仅供内部使用
void	Dispose ()
	GDir ()
	Creates a direction corresponding to X axis.
	GDir (GVec theV)
	Normalizes the vector theV and creates a direction. Raises ConstructionError if theV.Magnitude() <= Resolution.
	GDir (GXYZ theCoord)
	Creates a direction from a triplet of coordinates. Raises ConstructionError if theCoord.Modulus() <= Resolution from gp.
	GDir (double theXv, double theYv, double theZv)
	Creates a direction with its 3 cartesian coordinates. Raises ConstructionError if Sqrt(theXv*theXv + theYv*theYv + theZv*theZv) <= Resolution Modification of the direction's coordinates If Sqrt (theXv*theXv + theYv*theYv + theZv*theZv) <= Resolution from gp where theXv, theYv ,theZv are the new coordinates it is not possible to construct the direction and the method raises the exception ConstructionError.
void	SetCoord (int theIndex, double theXi)
	For this unit vector, assigns the value Xi to: - the X coordinate if theIndex is 1, or - the Y coordinate if theIndex is 2, or - the Z coordinate if theIndex is 3, and then normalizes it. Warning Remember that all the coordinates of a unit vector are implicitly modified when any single one is changed directly. Exceptions Standard_OutOfRange if theIndex is not 1, 2, or 3. Standard_ConstructionError if either of the following is less than or equal to gp::Resolution(): - Sqrt(Xv*Xv + Yv*Yv + Zv*Zv), or - the modulus of the number triple formed by the new value theXi and the two other coordinates of this vector that were not directly modified.
void	SetCoord (double theXv, double theYv, double theZv)
	For this unit vector, assigns the values theXv, theYv and theZv to its three coordinates. Remember that all the coordinates of a unit vector are implicitly modified when any single one is changed directly.
void	SetX (double theX)
	Assigns the given value to the X coordinate of this unit vector.
void	SetY (double theY)
	Assigns the given value to the Y coordinate of this unit vector.
void	SetZ (double theZ)
	Assigns the given value to the Z coordinate of this unit vector.
void	SetXYZ (GXYZ theCoord)
	Assigns the three coordinates of theCoord to this unit vector.
double	Coord (int theIndex)
	Returns the coordinate of range theIndex : theIndex = 1 => X is returned Ithendex = 2 => Y is returned theIndex = 3 => Z is returned Exceptions Standard_OutOfRange if theIndex is not 1, 2, or 3.
void	Coord (ref double theXv, ref double theYv, ref double theZv)
	Returns for the unit vector its three coordinates theXv, theYv, and theZv.
double	X ()
	Returns the X coordinate for a unit vector.
double	Y ()
	Returns the Y coordinate for a unit vector.
double	Z ()
	Returns the Z coordinate for a unit vector.
GXYZ	XYZ ()
	for this unit vector, returns its three coordinates as a number triplea.
bool	IsEqual (GDir theOther, double theAngularTolerance)
	Returns True if the angle between the two directions is lower or equal to theAngularTolerance.
bool	IsNormal (GDir theOther, double theAngularTolerance)
	Returns True if the angle between this unit vector and the unit vector theOther is equal to Pi/2 (normal).
bool	IsOpposite (GDir theOther, double theAngularTolerance)
	Returns True if the angle between this unit vector and the unit vector theOther is equal to Pi (opposite).
bool	IsParallel (GDir theOther, double theAngularTolerance)
	Returns true if the angle between this unit vector and the unit vector theOther is equal to 0 or to Pi. Note: the tolerance criterion is given by theAngularTolerance.
double	Angle (GDir theOther)
	Computes the angular value in radians between <me> and <theOther>. This value is always positive in 3D space. Returns the angle in the range [0, PI]
double	AngleWithRef (GDir theOther, GDir theVRef)
	Computes the angular value between <me> and <theOther>. <theVRef> is the direction of reference normal to <me> and <theOther> and its orientation gives the positive sense of rotation. If the cross product <me> ^ <theOther> has the same orientation as <theVRef> the angular value is positive else negative. Returns the angular value in the range -PI and PI (in radians). Raises DomainError if <me> and <theOther> are not parallel this exception is raised when <theVRef> is in the same plane as <me> and <theOther> The tolerance criterion is Resolution from package gp.
void	Cross (GDir theRight)
	Computes the cross product between two directions Raises the exception ConstructionError if the two directions are parallel because the computed vector cannot be normalized to create a direction.
GDir	Crossed (GDir theRight)
	Computes the triple vector product. <me> ^ (V1 ^ V2) Raises the exception ConstructionError if V1 and V2 are parallel or <me> and (V1^V2) are parallel because the computed vector can't be normalized to create a direction.
void	CrossCross (GDir theV1, GDir theV2)
GDir	CrossCrossed (GDir theV1, GDir theV2)
	Computes the double vector product this ^ (theV1 ^ theV2). - CrossCrossed creates a new unit vector. Exceptions Standard_ConstructionError if: - theV1 and theV2 are parallel, or - this unit vector and (theV1 ^ theV2) are parallel. This is because, in these conditions, the computed vector is null and cannot be normalized.
double	Dot (GDir theOther)
	Computes the scalar product
double	DotCross (GDir theV1, GDir theV2)
	Computes the triple scalar product <me> * (theV1 ^ theV2). Warnings : The computed vector theV1' = theV1 ^ theV2 is not normalized to create a unitary vector. So this method never raises an exception even if theV1 and theV2 are parallel.
void	Reverse ()
GDir	Reversed ()
	Reverses the orientation of a direction geometric transformations Performs the symmetrical transformation of a direction with respect to the direction V which is the center of the symmetry.]
void	Mirror (GDir theV)
GDir	Mirrored (GDir theV)
	Performs the symmetrical transformation of a direction with respect to the direction theV which is the center of the symmetry.
void	Mirror (GAx1 theA1)
GDir	Mirrored (GAx1 theA1)
	Performs the symmetrical transformation of a direction with respect to an axis placement which is the axis of the symmetry.
void	Mirror (GAx2 theA2)
GDir	Mirrored (GAx2 theA2)
	Performs the symmetrical transformation of a direction with respect to a plane. The axis placement theA2 locates the plane of the symmetry : (Location, XDirection, YDirection).
void	Rotate (GAx1 theA1, double theAng)
GDir	Rotated (GAx1 theA1, double theAng)
	Rotates a direction. theA1 is the axis of the rotation. theAng is the angular value of the rotation in radians.
void	Transform (GTrsf theT)
GDir	Transformed (GTrsf theT)
	Transforms a direction with a "Trsf" from gp. Warnings : If the scale factor of the "Trsf" theT is negative then the direction <me> is reversed.
