The FindEdgeIslands method is a member of the PolygonMesh class in the Sandbox namespace. This method is used to identify and group connected edges into separate islands. An edge island is a set of edges that are connected to each other but not connected to any other edges outside the island.
To use the FindEdgeIslands method, you need to provide a list of edges as input. The method will output a list of edge islands, where each island is a list of connected edges.
Parameters:
edgeList: A read-only list of HalfEdgeMesh.HalfEdgeHandle representing the edges to be analyzed.outEdgeList: An output parameter that will contain a list of lists, where each inner list represents an edge island.// Example usage of FindEdgeIslands PolygonMesh polygonMesh = new PolygonMesh(); IReadOnlyList<HalfEdgeMesh.HalfEdgeHandle> edgeList = GetEdges(); // Assume this method retrieves a list of edges List<List<HalfEdgeMesh.HalfEdgeHandle>> edgeIslands = new List<List<HalfEdgeMesh.HalfEdgeHandle>>(); polygonMesh.FindEdgeIslands(edgeList, out edgeIslands); // edgeIslands now contains the grouped edge islands
