[vtkusers] Viusalization of registered images

[Jesús Spí­nola]

Hello,

I'm writting a medical imaging application that registers two datasets with
itk.

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.

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.

Thanks in advance
