[vtkusers] Problem with viewing vtkReebGraph

[Jim Peterson]

Mehdi,
I am using vtk 5.6.1. The vtkReeb.... classes are new with vtk 5.7.0. I 
don't know what to expect from them, so I cannot help there.

I assume you have the source, maybe there is an author link you could 
contact there.

good luck,
Hope that helps,
Jim
