[vtkusers] How can I save to STL format？

[noc]

Hi all,

 

Now, I'm doing marching cubes. I wanna save the resault(the 3D image) to STL format, 

I tried this:

--code--

vtkSTLWriter * writeSTL = vtkSTLWriter ::New();
  writeSTL->SetFileName("D:/data/feet.stl");
  writeSTL->SetInput(stripper->GetOutput());   //data from vtkStripper
  writeSTL->Write();

--code--

 

but it didn't work. The feet.stl is only 1KB.

However, I can see the 3D surface in RenderWindow. I don't konw why.

Could any one help me, please?

 

Thanks so much!!!

 

Regards,

 

Danile
