Thank you for both answers.
>I am not sure if I understand correctly what you want to see. In what way
is your goal different from our 3D view of our mitkWorkbench? (You can
rotate, swivel, etc. our planes with the >renderwindow menu on top of each
renderwindow.). If your goal is different, could you draw a sketch?
I want to be able to extract a slice from a 3D volume and to add that
(generally oblique) slice to the 3D view, without losing the three
"crosshair" planes.
Ivo interpreted my request correctly, this is what I see:
http://screencast.com/t/y6al4fS4X
"No name" is the volume, "Ivo's plane" is the that Ivo suggested to add in
the rendering. This is exactly what we wanted.
However we have found a new issue when we want to "extract" the slice:
http://screencast.com/t/LeOROaDU
The slice we extracted with ExtractSliceFilter is in red (it is a 2D image
just with zeros...), and after a reinit on the slice:
http://screencast.com/t/f7HSHnsC
Given that we are using the same geometry for Ivo's plane and for
ExtractSliceFilter, what could be going wrong?
