[vtkusers] apply vtktubes to unstructured mesh

[pablo p del castillo]

It seems better write scalar to create subdomains depending of the number of nodes per cell, and then with vtkThreshold select lines.

But it is strange that vtk has tools to extract edges, but not to select diferent cells based in their shape.

I am newbie in vtk.

Hello,

I have a unstructured mesh with triangles and lines, how can i extract lines to apply tubes.

Advanced thanks




Hmm, is there any reason why vtkTubeFilter derives from vtkPolyDataAlgorithm? It seems like if it could derive from vtkPointSetAlgorithm instead this question would be no problem.

Pablo, if you can get your lines into a vtkPolyData, you can use this method to get tubes on your lines:http://www.cmake.org/Wiki/VTK/Examples/TubeFilter

Thanks,

David
