[vtkusers] DataExtent ids to cell ids of hole extent

[Charles Monty Burns]

Hello,

I want to calculate all voxel ids of a vtkImageData that intersect with the
bounds of a tetrahedron of a mesh.

My idea, with vtk averages, is that I compute the structured coordinates of
the two boundary points an set the extent of the image to that points. Now I
can get all cells of that extent to extract some kind of data (e.g.
scalars), but I want to know the id of the cell of the whole extent.

Whats the best way to get this id's?

Greeting
