I try to realize CGAL 6.0.1 Straight Skeleton (SS) Extrude between two offset. A standard Extrude SS CGAL is taking an offset and weight (height) parameter:

In my case is required to add additional parameters offset1/weight1 and offset2/weight2:

I find out that a standard extrude calcs with function construct_lateral_faces (without caps):
.h#L509
I think this function can be modified for my case but I do not understand how to do this?
