0024 //! An algorithm to convert a sequence of adjacent
0025 //! non-rational Bezier curves into a BSpline curve.
0026 //! A CompBezierCurvesToBSplineCurve object provides a framework for:
0027 //! -   defining the sequence of adjacent non-rational Bezier
0028 //! curves to be converted into a BSpline curve,
0029 //! -   implementing the computation algorithm, and
0030 //! -   consulting the results.
0031 //! Warning
0032 //! Do not attempt to convert rational Bezier curves using this type of algorithm.
