[ITK-users] Rigid 3D rotation based on plane

[Matt McCormick]

Hi Jared,

It sounds like you just want to resample an image with a given
transformation.  Search for "Resample" on this page:

  http://www.itk.org/Insight/Doxygen/html/examples.html

consider the Euler3DTransform:

  http://www.itk.org/Insight/Doxygen/html/classitk_1_1Euler3DTransform.html

and see the section on Transforms in the ITK Software Guide:

  http://itk.org/ITKSoftwareGuide/html/Book2/ITKSoftwareGuide-Book2ch3.html#x26-1160003.9

HTH,
Matt
