Quote - A chain figure is handy for lengths lying around, i.e. not hanging between two points for which you might as well just have a prop (and regenerate if the end points move).

If you have any pointers for deriving the proper angles for positions along the catenary curve, I can think about trying to approach the hanging-between-two-points problem.  I explored the catenary problem yesterday and found some code which can give me the point set, but I'm not convinced I have the angles.  I posted an image last night of colored blocks in a catenary curve, but the rotations I derived from my interpretation of markschum's advice seem almost certainly incorrect.

Can you suggest how I can get the proper angles, given the plot points of the curve?  I'm afraid my formal math training is limited and I'm pressing against the edges of my knowledge, here.  :lol:

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.
