The bevel effect

I would like to apply this bevel effect to an existing typeface I’m creating. The effect seems like it would be possible with a mathematically-based foundation. Any recommendations on scripts or how I can start in general?

I don’t want to say it is impossible, cuz it ain’t. But you tackle a rather complex issue. Basically it’s the same as what Andy Clymer did for Obsidian, just in a less dissected manner. Maybe this video can give you some hints.
