The abstract class AxisPlacement describes the common behavior of positioning systems in 3D space, such as axis or coordinate systems. The Geom package provides two implementations of 3D positioning systems: More...
#include <Geom_AxisPlacement.hxx>
Public Member Functions  
void  SetAxis (const gp_Ax1 &A1) 
Assigns A1 as the "main Axis" of this positioning system. This modifies. More...  
virtual void  SetDirection (const gp_Dir &V)=0 
Changes the direction of the axis placement. If <me> is an axis placement two axis the main "Direction" is modified and the "XDirection" and "YDirection" are recomputed. Raises ConstructionError only for an axis placement two axis if V and the previous "XDirection" are parallel because it is not possible to calculate the new "XDirection" and the new "YDirection". More...  
void  SetLocation (const gp_Pnt &P) 
Assigns the point P as the origin of this positioning system. More...  
Standard_Real  Angle (const Handle< Geom_AxisPlacement > &Other) const 
Computes the angular value, in radians, between the "main Direction" of this positioning system and that of positioning system Other. The result is a value between 0 and Pi. More...  
const gp_Ax1 &  Axis () const 
Returns the main axis of the axis placement. For an "Axis2placement" it is the main axis (Location, Direction ). For an "Axis1Placement" this method returns a copy of <me>. More...  
gp_Dir  Direction () const 
Returns the main "Direction" of an axis placement. More...  
gp_Pnt  Location () const 
Returns the Location point (origin) of the axis placement. More...  
Public Member Functions inherited from Geom_Geometry  
void  Mirror (const gp_Pnt &P) 
Performs the symmetrical transformation of a Geometry with respect to the point P which is the center of the symmetry. More...  
void  Mirror (const gp_Ax1 &A1) 
Performs the symmetrical transformation of a Geometry with respect to an axis placement which is the axis of the symmetry. More...  
void  Mirror (const gp_Ax2 &A2) 
Performs the symmetrical transformation of a Geometry with respect to a plane. The axis placement A2 locates the plane of the symmetry : (Location, XDirection, YDirection). More...  
void  Rotate (const gp_Ax1 &A1, const Standard_Real Ang) 
Rotates a Geometry. A1 is the axis of the rotation. Ang is the angular value of the rotation in radians. More...  
void  Scale (const gp_Pnt &P, const Standard_Real S) 
Scales a Geometry. S is the scaling value. More...  
void  Translate (const gp_Vec &V) 
Translates a Geometry. V is the vector of the tanslation. More...  
void  Translate (const gp_Pnt &P1, const gp_Pnt &P2) 
Translates a Geometry from the point P1 to the point P2. More...  
virtual void  Transform (const gp_Trsf &T)=0 
Transformation of a geometric object. This tansformation can be a translation, a rotation, a symmetry, a scaling or a complex transformation obtained by combination of the previous elementaries transformations. (see class Transformation of the package Geom). More...

Standard_Transient ()  
Empty constructor. More...  
Standard_Transient (const Standard_Transient &)  
Copy constructor – does nothing. More...  
Standard_Transient &  operator= (const Standard_Transient &) 
Assignment operator, needed to avoid copying reference counter. More...

The abstract class AxisPlacement describes the common behavior of positioning systems in 3D space, such as axis or coordinate systems. The Geom package provides two implementations of 3D positioning systems:
Standard_Real Geom_AxisPlacement::Angle  (  const Handle< Geom_AxisPlacement > &  Other  )  const 
Computes the angular value, in radians, between the "main Direction" of this positioning system and that of positioning system Other. The result is a value between 0 and Pi.
const gp_Ax1& Geom_AxisPlacement::Axis  (  )  const 
Returns the main axis of the axis placement. For an "Axis2placement" it is the main axis (Location, Direction ). For an "Axis1Placement" this method returns a copy of <me>.
gp_Dir Geom_AxisPlacement::Direction  (  )  const 
Returns the main "Direction" of an axis placement.
gp_Pnt Geom_AxisPlacement::Location  (  )  const 
Returns the Location point (origin) of the axis placement.
void Geom_AxisPlacement::SetAxis  (  const gp_Ax1 &  A1  ) 
Assigns A1 as the "main Axis" of this positioning system. This modifies.

pure virtual 
Changes the direction of the axis placement. If <me> is an axis placement two axis the main "Direction" is modified and the "XDirection" and "YDirection" are recomputed. Raises ConstructionError only for an axis placement two axis if V and the previous "XDirection" are parallel because it is not possible to calculate the new "XDirection" and the new "YDirection".
Implemented in Geom_Axis2Placement, and Geom_Axis1Placement.
void Geom_AxisPlacement::SetLocation  (  const gp_Pnt &  P  ) 
Assigns the point P as the origin of this positioning system.
