Hi everybody
 
I am having a problem displaying an image. I want to read the image an 
create a 3D image from it.  The script is OK and the display window 
appears but there is no rendering in the window, the window is just empty. 
Can someone please help me ?
 
thanks for your help
thomas

package require vtklocal
 
vtkTIFFReader r1
r1 SetFileName "tazc.tif"
 
vtkImageDataGeometryFilter itop
itop SetInput [r1 GetOutput]

vtkWindowLevelLookupTable look
 
vtkPolyDataMapper m
