[IGSTK-Users] 3D Reconstruction.

[Patrick Cheng]

Hi Ashwath,

I think you are referring to the lower left image viewer. That one is 
using volume rendering.

You are correct, ITK-SNAP does not have volume rendering. You can try 
VolView:

There is also an old example in IGSTKSandbox that supports volume rendering.

IGSTKSandbox/Examples/DeckOfCardRobot

The screenshot of this application is on page 330 of the book:
