hi,

I use the hds data structure and have a special surface which has a
self-intersecting contact in one point. Imagine two cube have a contact in a
corner - say C and my HDS identifies this as a single point. 
C->halfedge() returns an arbitrary  halfedge. 
My question is: How can I surround the vertex C and getting all connected
halfedges and not only one side of the surface?
How can I easily identify whether I have this special case?


tx for your help,

Franki
