[Pasquale De Stefano]

hi all i am newbie to VTK i have some simple questions..
I have a series of dicom and using itk , vtk i can show them and also have a
surface rendering using filters..(as interface i am using wxwidgets)

after using many filters i get a mapper and i create an actor on wich i set
this mapper.So i have  an actor, when i show my 3d image i just add this
actor to the renderer that is bind to the render window that is bind to a
wxvtk interactor...
I hope is all clear..
Now the questions..

1) when i am looking the 3d image if i press a i cant interract with the
image that is frozen,...  what does it mean?? (if i press c all work fine..)


2) from the 3d image i want to get an image that is my
coronal-axial-sagittal view..

I found this..
http://www.gup.uni-linz.ac.at/crossgrid/gvk/vtkvideo/MedicalVid.cxx
there is a sample code that explain how to get a axial sagittal or coronal
view..
but for me is so hard.. How can I get a  vtkImageData from the actor ( and
selecting an axial or coronal or sagittal view) ?

i think i must draw a plane that cut my 3d model and get the image view from
that plane..

how??
