[vtkusers] unstructured grid to rectilinear grid

[Eric E. Monson]

Hello Eugen,

It sounds like you should be able to use the vtkProbeFilter:

http://www.vtk.org/doc/nightly/html/classvtkProbeFilter.html

Which can take in your Unstructured Grid (as "input") and probe it at  
the points of an ImageData (as "source"). Sorry I don't have a simple  
example handy, but there are some linked from the Doxygen page.
