[vtkusers] Is there a filter that can interpolate unstructed data to structed data? like griddata() in MATLAB

[Bryn Lloyd]

You Could use vtkImplicitDataset.
http://www.vtk.org/doc/nightly/html/classvtkImplicitDataSet.html

Iterate over the points of the structured grid and interpolate the value
at the points by calling "EvaluateFunction (double x[3])"
