Is there a way to either<br>
1) associate a coordinate with each vertex in a graph/tree?<br>
or<br>
2) create a polydata from a graph/tree where in the process a<br>
coordinate gets assigned a vertex?<br>
<br>
I would like to visualize a nearest neighbor graph on a set of 3d<br>
points. Can anyone point me to the right keywords/classes/functions to<br>
do such a thing?<br></blockquote><div><br></div><div> </div></div>vtkGraphLayout algorithm assigns points to a graph. You can also do this manually by:<div><br></div><div>vtkPoints* pts = vtkPoints::New();</div><div>pts->SetNumberOfPoints(graph->GetNumberOfVertices());</div>
<div>// Fill in points here</div><div>graph->SetPoints(pts);</div><div><br></div><div>Jeff<br><br></div>
