[vtkusers] question about the interpolation in the vtkImageReslice

[Anja Ende]

Hi everyone,

I have a question about the vtkImageReslice tricubic interpolation
alogorithm. Just trying to figure out what it actually does:

So, I am guessing it takes the weighted average of the nearby pixels. Just
wondering how many pixels it takes into account. Is it a 4x4x4 grid
(effectively 64 pixels and 3 cubic polynomials)?

Thanks for any help you might give me.

Cheers,

Anja
