Hi all,<BR>
I used vtkDelaunay2D to get a mesh and use vtkExtractEdges to get edges<BR>
...<BR>
vtkDelaunay2D del = vtkDelaunay2D::New();<BR>
...<BR>
vtkExtractEdges *extract = vtkExtractEdges::New();<BR>extract->SetInputConnection(del->GetOutputPort());<BR>
vtkPolyData *data = extract->GetOutput();<BR>
vtkCellArray *lineArray = data->GetLines();<BR>
<BR>
If I want to get all lines from the lineArray, should I use functions like GetNextCell() and InitTraversal()<BR>
Can someone give me an example how GetNextCell() and InitTraversal() works? and esepecially the meaning of their parameters?<BR>
<BR>
<BR>
Thank you guys advance!<BR><BR><BR>
