class ApproxCurve from GeomConvert
|
|
---Purpose: A framework to convert a 3D curve to a 3D BSpline.
|
|
-- This is done by approximation to a BSpline curve within a given tolerance.
|
|
|
|
uses

Create (Curve: Curve from Geom;
|
|
Tol3d: Real;
|
|
Order: Shape from GeomAbs;
|
|
MaxSegments: Integer;
|
|
MaxDegree: Integer) returns ApproxCurve;
|
|
---Purpose: Constructs a curve approximation framework defined by -
|
|
-- - the conic Curve,
|
|
-- - the tolerance value Tol3d,
|
|
-- - the degree of continuity Order,
|
|
-- - the maximum number of segments
|
|
-- MaxSegments allowed in the resulting BSpline curve, and
|
|
-- - the highest degree MaxDeg which the
|
|
-- polynomial defining the BSpline curve may have.
|
|
|
|
Curve(me) returns BSplineCurve from Geom;
|
|
--- Purpose: Returns the BSpline curve resulting from the approximation algorithm.
|
|
|
|
IsDone(me) returns Boolean from Standard;
|
|
---Purpose: returns Standard_True if the approximation has
|
|
-- been done within requiered tolerance
|
|
|
|
HasResult(me) returns Boolean;
|
|
---Purpose: Returns Standard_True if the approximation did come out
|
|
-- with a result that is not NECESSARELY within the required tolerance
|
|
|
|
MaxError(me) returns Real from Standard;
|
|
---Purpose: Returns the greatest distance between a point on the
|
|
-- source conic and the BSpline curve resulting from the
|
|
-- approximation. (>0 when an approximation
|
|
-- has been done, 0 if no approximation)
