class PConic from IntCurve
---Purpose: This class represents a conic from gp as a
-- parametric curve ( in order to be used by the
-- class PConicTool from IntCurve).
---Level: Internal
uses Elips2d from gp,
Lin2d from gp,
Circ2d from gp,
Parab2d from gp,
Hypr2d from gp,
Ax22d from gp,
CurveType from GeomAbs
is
Create(PC: PConic from IntCurve) returns PConic from IntCurve;
Create(E: Elips2d from gp) returns PConic from IntCurve;
Create(C: Circ2d from gp) returns PConic from IntCurve;
Create(P: Parab2d from gp) returns PConic from IntCurve;
Create(H: Hypr2d from gp) returns PConic from IntCurve;
Create(L: Lin2d from gp) returns PConic from IntCurve;
SetEpsX(me: in out; EpsDist: Real from Standard) is static;
---Purpose: EpsX is a internal tolerance used in math
-- algorithms, usually about 1e-10
-- (See FunctionAllRoots for more details)
SetAccuracy(me: in out; Nb: Integer from Standard) is static;
---Purpose: Accuracy is the number of samples used to
-- approximate the parametric curve on its domain.
Accuracy(me)
---C++: inline
returns Integer from Standard is static;
EpsX(me)
---C++: inline
returns Real from Standard is static;
TypeCurve(me)
---Purpose: The Conics are manipulated as objects which only
-- depend on three parameters : Axis and two Real from Standards.
-- Type Curve is used to select the correct Conic.
