is static;
D2 (me; U: Real from Standard ; P: out Pnt2d; T,N: out Vec2d)
is static;
Distance(me; P: Pnt2d)
---Purpose: Computes the value of the signed distance between
-- the point P and the implicit curve.
returns Real from Standard
is static;
GradDistance(me; P: Pnt2d)
---Purpose: Computes the Gradient of the Signed Distance
-- between a point and the implicit curve, at the
-- point P.
returns Vec2d from gp
is static;
FindParameter(me; P: Pnt2d)
---Purpose: Returns the parameter U of the point on the
-- implicit curve corresponding to the point P. The
-- correspondance between P and the point P(U) on the
-- implicit curve must be coherent with the way of
-- determination of the signed distance.
