class openvdb::v12_1::tools::lvlset::TriangleMeshEdgeConnectivity< ValueT >
Class representing the connectivity of edges in a triangle mesh, where each edge is associated with the cells (triangles) sharing it. Provides methods to retrieve adjacent cells, vertex coordinates, normals, and other geometric properties.
Constructs the TriangleMeshEdgeConnectivity object with given coordinates and cell data. Populates edge-to-cell adjacency and computes cell normals.

Retrieves the total number of cells (triangles) in the mesh.
- Returns
- The number of cells as an Index.
Retrieves the total number of coordinates in the mesh.
- Returns
- The number of coordinates as an Index.
