Thanks for your help. The way you mentioned did help, and I got some values
and visualised them. Unfortunately, the result does not look right. The left
image is the result and the right is the one computed by MeshLab.

I wonder if it is because of some other mistakes I made in my code or just
because of this function. Can we get reasonable normals with
compute_vertex_normal functions? And there is another overload of this
function with one more parameter, called "NamedParameters". Would this
matter?
