[vtkusers] How to determine if a loop is closed or not

[Shyam Prakash]

Mathieu,

> 	You can use vtkFeaturesEdges for this.

	Sorry for the mail format problem. I use vtkFeatureEdges to
extract the special type of edges from my polydata. But I am not sure
how to use this class to find out if a polygon is closed or not. Can you
please give me an example.

Thanks
Shyam
