Standard_EXPORT | gp_Ax3 () |
Creates an indefinite coordinate system. . | |
Standard_EXPORT | gp_Ax3 (const gp_Ax2 &A) |
Creates a coordinate system from a right-handed coordinate system. . | |
Standard_EXPORT | gp_Ax3 (const gp_Pnt &P, const gp_Dir &N, const gp_Dir &Vx) |
Creates a right handed axis placement with the "Location" point P and two directions, N gives the "Direction" and Vx gives the "XDirection". Raises ConstructionError if N and Vx are parallel (same or opposite orientation). . | |
Standard_EXPORT | gp_Ax3 (const gp_Pnt &P, const gp_Dir &V) |
Creates an axis placement with the "Location" point | |
Standard_EXPORT void | XReverse () |
Reverses the X direction of <me>. . | |
Standard_EXPORT void | YReverse () |
Reverses the Y direction of <me>. . | |
Standard_EXPORT void | ZReverse () |
Reverses the Z direction of <me>. . | |
Standard_EXPORT void | SetAxis (const gp_Ax1 &A1) |
Assigns the origin and "main Direction" of the axis A1 to this coordinate system, then recomputes its "X Direction" and "Y Direction". Note: - The new "X Direction" is computed as follows: new "X Direction" = V1 ^(previous "X Direction" ^ V) where V is the "Direction" of A1. - The orientation of this coordinate system (right-handed or left-handed) is not modified. Raises ConstructionError if the "Direction" of <a1> and the "XDirection" of <me> are parallel (same or opposite orientation) because it is impossible to calculate the new "XDirection" and the new "YDirection". . | |
Standard_EXPORT void | SetDirection (const gp_Dir &V) |
Changes the main direction of this coordinate system, then recomputes its "X Direction" and "Y Direction". Note: - The new "X Direction" is computed as follows: new "X Direction" = V ^ (previous "X Direction" ^ V). - The orientation of this coordinate system (left- or right-handed) is not modified. Raises ConstructionError if <V< and the previous "XDirection" are parallel because it is impossible to calculate the new "XDirection" and the new "YDirection". . | |
Standard_EXPORT void | SetLocation (const gp_Pnt &P) |
Changes the "Location" point (origin) of <me>. . | |
Standard_EXPORT void | SetXDirection (const gp_Dir &Vx) |
Changes the "Xdirection" of <me>. The main direction "Direction" is not modified, the "Ydirection" is modified. If <vx> is not normal to the main direction then <xdirection> is computed as follows XDirection = Direction ^ (Vx ^ Direction). Raises ConstructionError if <vx> is parallel (same or opposite orientation) to the main direction of <me> . | |
void | SetYDirection (const gp_Dir &Vy) |
Changes the "Ydirection" of <me>. The main direction is not modified but the "Xdirection" is changed. If <vy> is not normal to the main direction then "YDirection" is computed as follows YDirection = Direction ^ (<vy> ^ Direction). Raises ConstructionError if <vy> is parallel to the main direction of <me> . | |
Standard_Real | Angle (const gp_Ax3 &Other) const |
Computes the angular value between the main direction of <me> and the main direction of <other>. Returns the angle between 0 and PI in radians. . | |
const gp_Ax1 & | Axis () const |
Returns the main axis of <me>. It is the "Location" point and the main "Direction". . | |
Standard_EXPORT gp_Ax2 | Ax2 () const |
Computes a right-handed coordinate system with the same "X Direction" and "Y Direction" as those of this coordinate system, then recomputes the "main Direction". If this coordinate system is right-handed, the result returned is the same coordinate system. If this coordinate system is left-handed, the result is reversed. . | |

Standard_EXPORT void | Mirror (const gp_Pnt &P) |
Standard_EXPORT gp_Ax3 | Mirrored (const gp_Pnt &P) const |
Performs the symmetrical transformation of an axis placement with respect to the point P which is the center of the symmetry. Warnings : The main direction of the axis placement is not changed. The "XDirection" and the "YDirection" are reversed. So the axis placement stay right handed. . | |
Standard_EXPORT void | Mirror (const gp_Ax1 &A1) |
Standard_EXPORT gp_Ax3 | Mirrored (const gp_Ax1 &A1) const |
Performs the symmetrical transformation of an axis placement with respect to an axis placement which is the axis of the symmetry. The transformation is performed on the "Location" point, on the "XDirection" and "YDirection".

Standard_EXPORT void | Mirror (const gp_Ax2 &A2) |
Standard_EXPORT gp_Ax3 | Mirrored (const gp_Ax2 &A2) const |
Performs the symmetrical transformation of an axis placement with respect to a plane. The axis placement <a2> locates the plane of the symmetry : (Location, XDirection, YDirection). The transformation is performed on the "Location" point, on the "XDirection" and "YDirection".
