vtkUnstructuredGridToPolyDataFilter is an abstract class without a concrete implementation, so you can't actually use it in a program. Try vtkGeometryFilter.<div><br></div><div>- Wes<br><br><div class="gmail_quote">On Fri, Apr 1, 2011 at 10:22 AM, nuno.jf <span dir="ltr"><<a href="mailto:nunofernandes7@gmail.com">nunofernandes7@gmail.com</a>></span> wrote:<br>

(For now) I am using Paraview to delete the points that I don't want. After<br>
removing all these points, I save the file using Paraview as a legacy vtk<br>
file. As output I get an Unstructured Grid vtk file.<br>
I successfuly tested the example you had suggested me<br>
(<a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx#Surface_reconstruction" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx#Surface_reconstruction</a>) reading a<br>
structured VTK file, by changing some lines in the code.<br>
The problem is that I want to use this code to read an unstructured grid vtk<br>
file, so I added/changed the following in order to convert from unstructured<br>
grid to polydata:<br>
<br>
#include<br>
#include<br>
#include<br>
<br>
// read unstructured grid<br>
vtkUnstructuredGridReader *reader = vtkUnstructuredGridReader::New();<br>
reader->SetFileName(argv[1]);<br>
reader->Update();<br>
// create object<br>
vtkUnstructuredGrid * unstructured= vtkUnstructuredGrid::New();<br>
unstructured = reader ->GetOutput();<br>
unstructured ->Update();<br>
<br>
//convert to polydata<br>
vtkUnstructuredGridToPolyDataFilter *teste =<br>
vtkUnstructuredGridToPolyDataFilter::New();<br>
teste->SetInput(unstructured);<br>
teste->Update();<br>
<br>
Then, I get the following error:<br>
<br>
"error C2440: 'initializing' : cannot convert from 'vtkAlgorithm *' to<br>
'vtkUnstructuredGridToPolyDataFilter *' "<br>
<br>
What am I doing wrong here?<br>
Any help would be greatly appreciated.<br>
Best regards<br>
