gp_Dir () | |
Creates an indefinite direction. . | |
gp_Dir (const gp_Vec &V) | |
Normalizes the vector V and creates a direction. Raises ConstructionError if V.Magnitude() <= Resolution. . | |

Creates a direction from a triplet of coordinates. Raises ConstructionError if Coord.Modulus() <= Resolution from gp. . | |
gp_Dir (const Standard_Real Xv, const Standard_Real Yv, const Standard_Real Zv) | |
Creates a direction with its 3 cartesian coordinates. Raises ConstructionError if Sqrt(Xv*Xv + Yv*Yv + Zv*Zv) <= Resolution //! Modification of the direction's coordinates If Sqrt (X*X + Y*Y + Z*Z) <= Resolution from gp where X, Y ,Z are the new coordinates it is not possible to construct the direction and the method raises the exception ConstructionError. . | |
void | SetCoord (const Standard_Integer Index, const Standard_Real Xi) |
For this unit vector, assigns the value Xi to: - the X coordinate if Index is 1, or - the Y coordinate if Index is 2, or - the Z coordinate if Index is 3, and then normalizes it.

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 Xi and the two other coordinates of this vector that were not directly modified. . | |
void | SetCoord (const Standard_Real Xv, const Standard_Real Yv, const Standard_Real Zv) |

Standard_Boolean | IsEqual (const gp_Dir &Other, const Standard_Real AngularTolerance) const |
Returns True if the angle between the two directions is lower or equal to AngularTolerance. . | |
Standard_Boolean | IsNormal (const gp_Dir &Other, const Standard_Real AngularTolerance) const |

Standard_Boolean | IsParallel (const gp_Dir &Other, const Standard_Real AngularTolerance) const |
Returns true if the angle between this unit vector and the unit vector Other is equal to 0 or to Pi. Note: the tolerance criterion is given by AngularTolerance. . | |
Standard_EXPORT Standard_Real | Angle (const gp_Dir &Other) const |
Computes the angular value in radians between <me> and <other>. This value is always positive in 3D space. Returns the angle in the range [0, PI] . | |
Standard_EXPORT Standard_Real | AngleWithRef (const gp_Dir &Other, const gp_Dir &VRef) const |
Computes the angular value between <me> and <other>. <vref> is the direction of reference normal to <me> and <other> and its orientation gives the positive sense of rotation. If the cross product <me> ^ <other> has the same orientation as <vref> the angular value is positive else negative. Returns the angular value in the range -PI and PI (in radians). Raises DomainError if <me> and <other> are not parallel this exception is raised when <vref> is in the same plane as <me> and <other> The tolerance criterion is Resolution from package gp. . | |
void | Cross (const gp_Dir &Right) |

void | operator^= (const gp_Dir &Right) |
gp_Dir | Crossed (const gp_Dir &Right) const |
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. . | |

gp_Dir | CrossCrossed (const gp_Dir &V1, const gp_Dir &V2) const |
Computes the double vector product this ^ (V1 ^ V2). - CrossCrossed creates a new unit vector. Exceptions Standard_ConstructionError if: - V1 and V2 are parallel, or - this unit vector and (V1 ^ V2) are parallel.
