[vtkusers] inhomogeneous image transform

[Jeff Weiss]

I need to apply an inhomogeneous transformation (warping) to a 3D image
dataset.  The transformation is vector displacements of the voxel
corners defined in the coordinate system of the image/voxels.  After
transformation, I would like to resample the warped image back onto the
same image voxel grid and output it.

I have looked at vtkImageReslice, and vtkTransformToGrid, and I think
that in theory there should be a way to do this in vtk, but have not
been able to get anywhere, mainly because I can't find any relevant
examples.  I am looking for ideas/suggestions as to how to implement
this image processing pipeline.

Thanks in advance,

Jeff
