[vtkusers] Help!! Vtk 3D Image questions

[Arsene ELLA]

Hi there,

1) Displaying a 3D image slice (from "C:\\......\Data\\headsq\\quarter") in 
a view
port as following :

----------------------
:
:
  vtkImager *imager1;
  imager1 = vtkImager::New();
  imager1->AddActor2D(actor1);
  imager1->SetViewport(0.5, 0.0, 1.0, 0.5);
:
:
----------------------
the slice image appears too small than the view port. How can I do to 
enlarge the
image to fit the view port?

2) How can I associate a color palette to a 3D image and display its slices 
with
the corresponding color scalar bar?

3) I get the 3D medical image (like a MRI head), how can I represent it as a
     volume, and graphical rendering (3D surface representation) in VTK?

Thanks in advance

Arsene
