[vtkusers] world coordinates and image data

[Richard Beare]

Hi,
I'm trying to track down appropriate vtk data representations for
displaying multiple image data sets in correct relationships to one
another. The source data is MRI slices.

Does the vtkImageData type have the option of image axes not being
aligned to world coordinates? I haven't been able to see any way of
doing this.

Assuming this isn't possible, what is the most appropriate data
structure to use. The approach I'm thinking of is to iterate over the
image in ITK, looking up world coordinates for each voxel, and
building a large vtk data structure that I'd then save in a paraview
compatible format.

Any recommendations?
