[IGSTK-Users] 3D Reconstruction.

[Ashwath Hegde, ERS-HCLTech]

Hi Patrick,

Thanks for the reply mail.

Please find the attached image viewer screenshot.
The 3D view in the viewer is displaying an overlay of the segmented portion as  3D segment along with the transparent head region.

We have a doubt whether this kind of display is possible using ITK-SNAP.
Kindly help us on this issue.

Thanks and Regards,
Ashwath

By 3D, you mean display the contour of an anatomic structure using mesh 
right?

If that's the case, It think the best way is to segment in ITK-SNAP, 
save it as mesh, and then load it with igstkMeshObjectReader and display 
it. You can find some code in Navigator example for read and display the 
mesh.
