Hi,

Does itk library contain methods for resampling non-uniformly spaced =
data?

Actually, I would like to use Itk to do the following task:
given a set of non-uniformly spaced 2D data (data that could
be represented in itk as a PointSet or a Mesh), I would like
to generate a 2D image with isotropic pixels.=20

I think the basic super class to look for should be a MeshToImageFilter
or a PointSetToImageFilter, but these classes are not implemented
in itk.

Is there an alternative approched already implemented?

Many thanks for your help,

Georges
