Hi Stefan,
mitk::ClosedSpline and mitk::RingSpline were indeed only used for
experimental purposes so far. Rather than trying to make these
deprecated classes work, a new and better designed approach to support
spline curve in MITK should be implemented when the need arises.
If you look for a spline implementation and do not care so much for
rendering in MITK, I'd suggest to use VTK classes (vtkParametricSpline,
vtkCardinalSpline) or the ITK b-spline implementation
itk::NonUniformBSpline (which does not directly interpolate control
points though).
If your main intention is visualization, you could use the MITK spline
mapper classes, namely mitk::SplineMapper2D and mitk::SplineVtkMapper3D.
They take an mitk::PointSet and connect adjacent points with a VTK
spline function.
In our internal MITK branch, we have implemented a basic framework for
interpolating and non-interpolating subdivision curves (data objects,
mappers, readers/writers). Although subdivision is technically quite
different from spline interpolation, the visual result is very similar.
We are thinking about migrating these classes to the open source part of
MITK sooner or later. If you're interested in using subdivision curves
(and in helping us with making these classes open-source-ready :-)), let
us know!
Best regards,
Mathias

What I'm looking for is to have the opportunity to interpolate between
and render a set of points by an implicit function, such as a spline.
Are there other classes in mitk that support interpolation between fixed
points?
