I think I've managed to space out the vertices more evenly, on the links.  The current posted script results are on the right, in both the rendered and wireframe parts of the attached image.  There's noticeable bunching of rings in the straight portions of the link, with resulting texture compression.  On the left, a revised spacing method seems to fend that off fairly effectively.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
