Convert_ParabolaToBSplineCurve Class Reference

This algorithm converts a parabola into a non rational B-spline
curve.
The parabola is a Parab2d from package gp with the parametrization
P (U) = Loc + F * (U*U * Xdir + 2 * U * Ydir) where Loc is the
apex of the parabola, Xdir is the normalized direction of the
symmetry axis of the parabola, Ydir is the normalized direction of
the directrix and F is the focal length.
KeyWords :
Convert, Parabola, BSplineCurve, 2D .

DEFINE_STANDARD_ALLOC Convert_ParabolaToBSplineCurve (const gp_Parab2d &Prb, const Standard_Real U1, const Standard_Real U2)
 The parabola Prb is limited between the parametric values U1, U2
and the equivalent B-spline curve as the same orientation as the
parabola Prb.
