[vtkusers] VTK for tree visualization: how to modify the visibility of individual vertex/edge

[Xinghua Lou]

Dear all,

I am developing some Infovis applications based on VTK by following the 
TreeLayout.cxx example in VTK/Examples/Infovis. One problem I have now 
is that I don' know how to modify the visibility of certain vertex or 
edge. I tried to google this question but can not find a clear answer. 
Can anyone give me some hints? Any suggestion is highly appreciated. 
Thank you.

Best,
Xinghua.
