[vtkusers] vtkExtractVOI and SetVOI() information

[Christos Dimitropoulos]

Hello everyone,

I have visualized a volume from CT scans (dcm files). What I want to do is to pick a subvolume with the mouse and display it. Can I use the <vtkExtractVOI> filter for this job? Moreover, how I can send information to this filter concerning the subvolume that I define with the mouse?

Thanks in advance, christos
