[vtkusers] How can I save to STL format？

[noc]

Thank u so much!

You're right, The STLWriter only writes triangles. If I use the following code, it works!

--code--

vtkSTLWriter * writeSTL = vtkSTLWriter ::New();
  writeSTL->SetFileName("D:/data/feet1.STL");
  writeSTL->SetInput(marchingcubes->GetOutput());    //data directly from Marching Cubes
  writeSTL->Write();
--code--

 

Thanks again!!!
