Wasnt there a vtkPolyDataSingleShortestPath available which did a similar thing? Is this the next implementation<br><br><div class="gmail_quote">On Wed, May 19, 2010 at 1:31 PM, Dajiang Zhu <span dir="ltr"><<a href="mailto:djzhu@uga.edu">djzhu@uga.edu</a>></span> wrote:<br>

on your existing code:<br>
<br>
Karthik - when you commit this, can you update the example to match/demonstrate?<br>
<br>
Dajiang - See inline below:<br>

</div>Where did you find that link? Was it just a mistake? Or does a link<br>
need to be fixed somewhere?<br>

I highly recommend you use smart pointers:<br>
<a href="http://www.vtk.org/Wiki/VTK/Tutorials/SmartPointers" target="_blank">http://www.vtk.org/Wiki/VTK/Tutorials/SmartPointers</a><br>
<br>
vtkSmartPointer<vtkPolyDataReader> TReader =<br>
vtkSmartPointer<vtkPolyDataReader>::New();<br>
<div><br>
> vtkPolyData* TsurfaceData=vtkPolyData::New();<br>
> TsurfaceData=TReader->GetOutput();<br>
<br>
</div>You should NOT create an object before assigning the output of the reader.<br>
<br>
Instead, simply do:<br>
vtkPolyData* TsurfaceData = TReader->GetOutput();<br>
<br>
Good luck,<br>
