The FindEdgeRing method is used to identify all the edges that form a ring with a specified edge in a polygon mesh. An edge ring is a sequence of edges that are connected through a loop of faces, effectively forming a continuous loop around a mesh.
To use the FindEdgeRing method, you need to provide a handle to a half-edge from which the edge ring search will begin. The method will populate the provided list with the handles of all edges that form the ring.
Parameters:
hEdge: A HalfEdgeMesh.HalfEdgeHandle representing the starting edge for the ring search.outEdgeList: An output parameter that will be filled with a list of HalfEdgeMesh.HalfEdgeHandle objects representing the edges in the ring.// Example usage of FindEdgeRing PolygonMesh mesh = new PolygonMesh(); HalfEdgeMesh.HalfEdgeHandle startEdge = ...; // Assume this is initialized List<HalfEdgeMesh.HalfEdgeHandle> edgeRing = new List<HalfEdgeMesh.HalfEdgeHandle>(); mesh.FindEdgeRing(startEdge, out edgeRing); // edgeRing now contains all the edges in the ring starting from startEdge.
