Hi everyone,<br>
<br>
I'm a vtk beginner and kind of despair of getting the values of an image to<br>
[0,1].<br>
<br>
I'm reading in a .raw-File with vtkImageReader, afterwards I want to do the<br>
Scaling so I can use vtkImageThreshold then (which still does not work the<br>
way i want it to either) to select a special range.<br>
Aftwerwards i do MarchingCubes (vtkMarchingCubes) to get a volume and render<br>
with the vtkRenderer after mapping with vtkPolyDataMapper and a vtkActor<br>
plus vtkProperty.<br>
<br>
I think I could use a LookUpTable but I'm not familiar with it in vtk.<br>
<br>
Thank you for responses.<br>
