Hi Wagner,
I did a little test with the code you sent and ended up with the
conclusion that it is vtkINRIA3D's fault.
What happens is that the vtkExtractVOI changes the whole extent of the
image. The vtkViewImage3D class was doing a very bad boundary check
(checking all minimal dimensions, i.e. min_x, min_y and min_z of the
image, with 0 and not the value returned by GetWholeExtent()).
Consequently, it happened that the view was looking for a position outside
the point buffer, which was causing the crash.
You can update your vtkINRIA3D copy and things should go back to order.
Hope this helps,
Pierre Fillard.
