Can I use CGAL to perform triangular mesh offsetting?

If not, can anyone suggest any other library/source-code that I can use to
perform the offset operation.

I want to create an envelope around triangulated geometry with a specified
clearance.

I can write the code to offset the vertices by using normals computed from
the facets. But, it would create many intersections in the mesh.

I found two papers that deal with triangular mesh offsetting, but couldn't
find the code. Here are the papers.

Can anyone suggest me any resource that I can use to offset a triangular
mesh?

Thanks.
