How to load a mesh from a file?#

Imagine instead of a mesh, you want to handle point clouds.
(We emulate this use case by writing the above mesh to disk.)
In [3]:
filename = tempfile.NamedTemporaryFile(mode="w+t", delete=True, suffix=".ply").name
meshio.write(filename, meshio.Mesh(points=mesh.vertices, cells=[]))

point_cloud = PointCloud.from_file(filename)
point_cloud.n_vertices
