Constructor & Destructor Documentation

◆ gp_Ax22d() [1/4]

gp_Ax22d::gp_Ax22d ( )
inline

const gp_Dir2d theVy 
)
inline

Creates a coordinate system with origin theP and where:

  • theVx is the "X Direction", and
  • the "Y Direction" is orthogonal to theVx and oriented so that the cross products theVx^"Y Direction" and theVx^theVy have the same sign. Raises ConstructionError if theVx and theVy are parallel (same or opposite orientation).

gp_Ax22d::gp_Ax22d ( const gp_Pnt2d theP,
const gp_Dir2d theV,
const Standard_Boolean  theIsSense = Standard_True 
)
inline

Creates - a coordinate system with origin theP and "X Direction" theV, which is:

  • right-handed if theIsSense is true (default value), or
  • left-handed if theIsSense is false

◆ gp_Ax22d() [4/4]

gp_Ax22d::gp_Ax22d ( const gp_Ax2d theA,
const Standard_Boolean  theIsSense = Standard_True 
)
inline

Creates - a coordinate system where its origin is the origin of theA and its "X Direction" is the unit vector of theA, which is:

  • right-handed if theIsSense is true (default value), or
  • left-handed if theIsSense is false.
