I was referring the paper Virtual Node Algorithm for Changing Mesh Topology During Simulation .
I have one very basic question regarding it. A node one ring is been used in this paper. I am confused as to what it refers to .
Context in which it is used is in :
For each distinct scoop cut out of a node’s one ring, a virtual copy of the
central node is created and donated to the nodes within the given scoop
to give the mesh the degrees of freedom needed to break apart.
Please help to understand the same .
A node's one ring means the set of triangles that are incident on the node. If just read that paper recently, if you have any question, you can post on the comments
