[vtk-developers] InfoVis graph visualization question: vtkGraphLayoutView with a "Simple 2D" layout strategy

[David Cole]

This VTK wiki example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/InfoVis/XGMLReader

Yields this different rendering test failure on my dashboard machine:
http://open.cdash.org/testDetails.php?test=271695203&build=3430870

The graph structure looks the same, and the visual is roughly 
equivalent, but the expected image clearly shows a perfectly square 
glyph at each graph node. In my test image, the graph nodes look like 
they vary from circle to square to polygons in between...

What determines the shape of the node glyph in a vtkGraphLayoutView 
with a "Simple 2D" layout strategy? And would the shape difference 
account entirely for the slight offset and angle between expected image 
and test image...?


Thanks,
David C.
