[Insight-developers] Evaluators : Lagrange, Hermite, Bezier

[Luis Ibanez]

Jim,

That's right,
They fit perfectly as derived classes of  itk::SpatialFunction.

So, how about the following names:

- itk::LegendrePolynomialSpatialFunction
- itk::HermitePolynomialSpatialFunction
- itk::BersteinPolynomialSpatialFunction
- itk::SerendipityPolynomialsSpatialFunction

and maybe rename itkMultivariateLegendrePolynomial as

- itk::LegendrePolynomialSpatialFunction

It seems redundant to add "Multivariate" since
they will be N-D . This last class will need some reworking
because currently it is only supporting 2D and 3D.

By combining this Functions with Neighborhood operators
we can get a family of interpolators (with similar names )
and make them available for more combinatorial options in
the registration framework.   Currently we only have
NearesNeighbor, Linear and BSpline interpolators.



Thanks.

    Luis
