| Tries to minimize the sum (square(||Qui - Bi*Pi||)) where Pui describe the approximating Bezier curves'Poles and Qi the MultiLine points with a parameter ui. In this algorithm, the parameters ui are the unknowns. The tolerance required on this sum is given by Tol. The desired degree of the resulting curve is Deg. | |
| Standard_Boolean | IsDone () const |
| returns True if all has been correctly done. | |
| AppParCurves_MultiCurve | Value () const |
| returns all the Bezier curves approximating the MultiLine SSP after minimization of the parameter. | |
| Standard_Real | Error (const Standard_Integer Index) const |
| returns the difference between the old and the new approximation. An exception is raised if NotDone. An exception is raised if Index<1 or Index>NbParameters. | |
| Standard_Real | MaxError3d () const |
| returns the maximum difference between the old and the new approximation. | |
| Standard_Real | MaxError2d () const |
| returns the maximum difference between the old and the new approximation. | |
| Standard_Real | AverageError () const |
| returns the average error between the old and the new approximation. | |
