Detailed Description

The CCSTCurveBuilder class generates a B-Spline Curve from a CST parameterization.

Member Enumeration Documentation

Algorithm

enum class tigl::CCSTCurveBuilder::Algorithm

strong

The Algorithm enum gives a choice of the method.

Piecewise_Chebychev_Approximation subdivides the curve into segments, where each segment is approximated using a Chebychev polynomials. The final result is the C1 concatenation of these polynomials to a B-Spline

GeomAPI_PointsToBSpline uses OCCT's internal approximation algorithm to create a B-Spline that approximates a CST Curve.
