Thanks for your help Anja,<br><br>Store a map? I'm working on python at the moment and my current bodge is to store an additional python list with the points in it and check against this list, this seems a little wasteful on memory. I guess this isn't what you mean?

Hi,<br><br>Use vtkPoints::GetNumberOfPoints() to check this.<br><br>so, <br><br>if (myPointCollection->GetNumberOfPoints() == 0)<br> myPointCollection->InsertPoint(.....)<br><br>Cheers,<br><span>Anja<br>
