at vtkImageCheckerboard and vtkImageRectilinearWipe. They allow side-by-side

overlay them.</FONT></SPAN></DIV>

images<BR><BR></FONT></DIV>Hello,<BR><BR>I'm writting a medical imaging
application that registers two datasets with itk. <BR><BR>Now I want to view
the overlapped volumes with vtk. My intention is to view at the same time the
two datasets in a 2D representation where I can change the slice of both
volumes and control the opacity of each one, so I can view both volumes with
an opacity of 50%-50% ( by default ), or another possibilities like 30%-70%,
60%-40%, etc.<BR><BR>My question is: wich is the best way to do this with VTK?
Which classes do you recomend to achieve this? I tried with vtkImageViewer but
I don't know how to see two vtkImage at the same time or how to control
oppacity.<BR><BR>Thanks in advance<BR><BR></BLOCKQUOTE></BODY></HTML>
