Convert_ConicToBSplineCurve Class Reference

Root class for algorithms which convert a conic curve into
a BSpline curve (CircleToBSplineCurve, EllipseToBSplineCurve,
HyperbolaToBSplineCurve, ParabolaToBSplineCurve).
These algorithms all work on 2D curves from the gp
package and compute all the data needed to construct a
BSpline curve equivalent to the conic curve. This data consists of:
