The data is in a single .raw file. I would like to be able to read a portion of this file, resample the data and then either insert into vtkVolume or add to a single file. Basically the idea is to take the volume and resample it and put it into a single file(the whole resampled volume) by iterating through the original large .raw file and then render this smaller volume. And then be able to return to the smaller volume to resample it or change its spacing, etc. from a vtkImageReader. Is there a way to do this using vtkImageReader?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Sean<o:p></o:p></p></div></body></html>
