[vtkusers] Extract only bones or other tissues from a Ct

[wassim_belhadj at topnet.tn]

Hi ,

Thank you very much Michael for your help.

I'am using VTK 5.0.2, Microsoft Visual Studio and Qt 4.3.1.

I have just built and installed ITK 3.8.0.

I want to do something that looks like Osirix Imaging
Software(http://www.osirix-viewer.com/Snapshots.html),...

I would be delighted if you send me your cmake projects that combines
VTK/ITK using QT4 and VS.

Thank you in advance.

Regards,
