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

Wed Jan 28 13:29:04 EST 2004

Shyam,

	You can use vtkFeaturesEdges for this.

	Please could you send your mail as text ?

Thanks
Mathieu

Hi,
             I have a set of vtkLine cell types which form a loop (like
circle or ellipse etc. which may be closed or not). I want to find out
is this loop is closed or not. Does any body know how this can be
determined.

Thanks
Shyam
