[vtkusers] Marching cubes

[prabhat246]

Hello everyone,

I got the answer for my question from ITK forum.
in the example 
Well, I've changed the code 

     vtkContourFilter * contour = vtkContourFilter::New(); 
     contour->SetInput( vtkImporter2->GetOutput() ); 
     contour->SetValue(0, 128); 


to 

     vtkMarchingCubes * contour = vtkMarchingCubes::New(); 
     contour->SetInput(vtkImporter1->GetOutput()); 
     contour->SetValue(0, 128); 

It ensures me that now I get output only from Marching cubes algo. 
I am new to learn this algorithm. 


1. Can you please explain what are these parameters of SetValue function ?? 
2. How can I change the cube size to be bigger ?? and
3. Which file (and which function)has the actual code for the Marching cubes
algorithm???

Hoping for a helpful quick response
(I didn't get answer of my prev. question even after 15 days from VTK forum)

Thanks a lot

Prabhat
