The attribute is not saved into the OFF format, it is stored in a
property map (out_id in the code) and the example checks that after the
operation the values are correctly set.

I would like to have a union mesh retain the ids of each triangle;
i.e., which source mesh the triangle is from. This question was
raised on Feb. 5, 2018; and there was no solution at that time.

On July 25, 2018 "sloriot" posted new code that was to provide
such "id tracking":

corefinement_mesh_union_with_attributes.cpp

When I execute the code, the output mesh (union.off) seems to
contain info on vertices and face connectivity; but not attributes;
e.g. "color".

Suggestion(s)?

Thanks,
Tim
