Curve approximation with respect to tangencies
To approximate a curve with respect to tangencies, follow these steps:
Create an object of type AppDef_MultiPointConstraints from the set of points to approximate and use the method SetTang to set the tangency vectors.
Create an object of type AppDef_MultiLine from the AppDef_MultiPointConstraint.
Use AppDef_BSplineCompute which instantiates Approx_BSplineComputeLine to perform the approximation.
