[Insight-users] DigitallyReconstructedRadiograph

[MedVision]

Hi all,

   I'm new in ITK and I tried DRR generation according to the DigitallyReconstructedRadiograph1.cxx example. 
   My understanding is that the transform should be applied to the volume data. However in the example program it is noted: "<-t float float float>" as "translation parameter of the camera", I'm wondering whether it is the transformation for the volume or the camera.  As for the generated image, do I watch from the focalpoint facing the volume, or else ? 

   Thanks and Regards
