[vtkusers] Is it possible to move each pixel using a 3x3/4x4 matrix in VTK?

[Shashwath T.R.]

Hi Sheena,

I think if I get your question right, you'd probably have to use
vtkImageReslice (
http://www.vtk.org/doc/nightly/html/classvtkImageReslice.html). You can set
the reslice axes from a matrix, and set the output origin, extent and
spacing. It's a bit of a Swiss-army chainsaw, but it gets the job done.

Setting the transform on the volume, for example (as Dženan says) would
work for cases where you're translating, scaling or rotating. If you're
shearing, for example, it probably won't work. And this will not affect the
image; it'll only change the visualization. So if you want to use the
transformed data for something else, you'll need to use reslice.
