An edge is a connection between two vertices. In a half-edge mesh the edge is split into two half-edges with opposite orientation. Each half-edge stores the index to the terminating vertex, the next half-edge, the previous half-edge and the face it belongs to. The opposite half-edge is accessed implicitly. More...

Detailed Description

An edge is a connection between two vertices. In a half-edge mesh the edge is split into two half-edges with opposite orientation. Each half-edge stores the index to the terminating vertex, the next half-edge, the previous half-edge and the face it belongs to. The opposite half-edge is accessed implicitly.
