Detailed Description

This class implements the following algorithms used to create a Dir2d from gp.

Constructor & Destructor Documentation

gce_MakeDir2d::gce_MakeDir2d ( const gp_Vec2d V)

Normalizes the vector V and creates a direction. Status is "NullVector" if V.Magnitude() <= Resolution.

gce_MakeDir2d::gce_MakeDir2d ( const gp_XY Coord)

Creates a direction from a triplet of coordinates. Status is "NullVector" if Coord.Modulus() <= Resolution from gp.

gce_MakeDir2d::gce_MakeDir2d ( const Standard_Real  Xv,
const Standard_Real  Yv 
)

Creates a direction with its 3 cartesian coordinates. Status is "NullVector" if Sqrt(Xv*Xv + Yv*Yv ) <= Resolution.

gce_MakeDir2d::gce_MakeDir2d ( const gp_Pnt2d P1,
const gp_Pnt2d P2 
)

Make a Dir2d from gp <TheDir> passing through 2 Pnt <P1>,<P2>. Status is "ConfusedPoints" if <P1> and <P2> are confused. Warning If an error occurs (that is, when IsDone returns false), the Status function returns:

  • gce_ConfusedPoints if points P1 and P2 are coincident, or
  • gce_NullVector if one of the following is less than or equal to gp::Resolution():
  • the magnitude of vector V,
  • the modulus of Coord,
  • Sqrt(Xv*Xv + Yv*Yv).

const gp_Dir2d& gce_MakeDir2d::Operator ( ) const
gce_MakeDir2d::operator gp_Dir2d ( ) const
const gp_Dir2d& gce_MakeDir2d::Value ( ) const

Returns the constructed unit vector. Exceptions StdFail_NotDone if no unit vector is constructed.
