gp_Ax2 () | |
Creates an indefinite coordinate system. . | |
gp_Ax2 (const gp_Pnt &P, const gp_Dir &N, const gp_Dir &Vx) | |
Creates an axis placement with an origin P such that: - N is the Direction, and - the "X Direction" is normal to N, in the plane defined by the vectors (N, Vx): "X <br> Direction" = (N ^ Vx) ^ N, Exception: raises ConstructionError if N and Vx are parallel (same or opposite orientation). . | |
Standard_EXPORT | gp_Ax2 (const gp_Pnt &P, const gp_Dir &V) |
Creates - a coordinate system with an origin P, where V gives the "main Direction" (here, "X Direction" and "Y <br> Direction" are defined automatically). . | |
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. Exceptions Standard_ConstructionError if A1 is parallel to the "X <br> Direction" of this coordinate system. . | |
Standard_EXPORT void | SetDirection (const gp_Dir &V) |
Changes the "main Direction" of this coordinate system, then recomputes its "X Direction" and "Y Direction".

Standard_EXPORT 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).

Standard_EXPORT void | Mirror (const gp_Pnt &P) |
Performs a symmetrical transformation of this coordinate system with respect to: - the point P, and assigns the result to this coordinate system. Warning This transformation is always performed on the origin. In case of a reflection with respect to a point: - the main direction of the coordinate system is not changed, and - the "X Direction" and the "Y Direction" are simply reversed In case of a reflection with respect to an axis or a plane: - the transformation is applied to the "X Direction" and the "Y Direction", then - the "main Direction" is recomputed as the cross product "X Direction" ^ "Y Direction". This maintains the right-handed property of the coordinate system. . | |
