Class used to project a 3d curve on a plane. The
result will be a 3d curve.
You can ask the projected curve to have the same
parametrization as the original curve.
The projection can be done along every direction not
parallel to the plane.

ProjLib_ProjectOnPlane () | |
Empty constructor. | |
ProjLib_ProjectOnPlane (const gp_Ax3 &Pl) | |
The projection will be normal to the Plane defined by the Ax3 <Pl>. | |
ProjLib_ProjectOnPlane (const gp_Ax3 &Pl, const gp_Dir &D) | |
The projection will be along the direction <D> on the plane defined by the Ax3 <Pl>. //! raises if the direction <D> is parallel to the plane <Pl>. | |
void | Load (const Handle< Adaptor3d_HCurve > &C, const Standard_Real Tolerance, const Standard_Boolean KeepParametrization=Standard_True) |
Sets the Curve and perform the projection. if <KeepParametrization> is true, the parametrization of the Projected Curve <PC> will be the same as the parametrization of the initial curve . It | |
