[vtkusers] display .vtk files in window

[Sercani]

Hi;
You must first define a vtkCanvas for adding the vtk libraries to system 
memory and add this canvas to a JFrame's container...Read that .vtk file 
with a appropriate reader (same as the writer that you use before), 
define a vtkImageViewer2, add that readers output to his viewer's input 
and add this viewer to your canvas renderer:

vtkImageViewer2 viewer = new vtkImageViewer2();
viewer.SetColorWindow(256); //must be calculated like this: int window = 
(int) ((reader.GetOutput().GetScalarRange()[1] - 
reader.GetOutput().GetScalarRange()[0]));
viewer.SetColorLevel(128);    //must be calculated like this:  int level 
= (int) (reader.GetOutput().GetScalarRange()[0] + (window / 2));
viewer.SetInput(reader.GetOutput());
viewer.SetRenderWindow(canvas.GetRenderWindow());
viewer.SetRenderer(canvas.GetRenderer());

This viewer contains all of your images, you can use it for reslicing, 
window & level processing etc. Check out vtkImagePlaneWidget's examples 
for a convenient MPR projection, vtkFixedPointRayCastMapper for MIP and 
MINIP rendering, vtkPolyDataMapper and vtkImageMarchingCubes for SSD 
rendering, vtkVolumeTextureMapper3D for VRT rendering...

Namaste...
