[vtkusers] vtkImageReslice on data with uneven spacing

[Boxer, Aaron]

Thanks, David. Currently, I don't need to use any image filters or mappers.
I simply use vtkImageReslice to extract a 2D slice.

I tried changing my code to use vtkRectilinearGrid;
The only two calls that are not supported are

SetOrigin
And
SetSpacing.

How should I set these values?

Cheers,
Aaron

Not really.  You could use vtkRectilinearGrid to store the data, this allows uneven spacing and efficient storage but it means you cannot use the VTK image filters or mappers.  VTK would treat the CT as a generic data set.
