Hi,

There is vtkPointData for storing data associated with points, is there a corresponding way to store data associated with the edges of polygon/connectivity ?

Cheers

There is a way but it’s not as easy as it could be (i.e., not integrated into the appropriate vtkDataSet data model). Check out the various classes in Common/DataMode/ such as vtkEdgeTable, vtkGenericEdgeTable, vtkStaticEdgeLocatorTemplate.
