edge_index_to_triangles(edge_index)

Convert an edged index to triangle simplices (triplets of coordinate indices).

Parameters:

edge_index (ArrayLike) – An Nx2 array of edges.

Returns:

An Nx3 array of triangles.

Return type:

ArrayLike

Example

>>> points = np.random.rand(100, 2)
>>> adjacency = delaunay_adjacency(points)
>>> edge_index = affinity_to_edge_index(adjacency)
>>> triangles = edge_index_to_triangles(edge_index)
