divine spine vs. ribbon spine

[mlefevre]

hi guys!
i was just wondering, how many of you use ribbon and divine spine?
and i was also thinking which is better to use?

Can you provide some info on the divine spine setup?
I've never heard or seen anything of it!

divine spine setup (maya) was originally from Eric Miller,
which composes of a lo-res skeleton and hi-res skeleton(for binding)
i found this setup in a book (learning maya 5)

I haven't ever heard of a divine spine either, but the setup seems pretty simple. From what I remember of a ribbon spine, is that the controls behave more or less in an IK fashion. Meaning, you grab and manipulate a control, rather than use joint or object rotations.

Personally, I like to use a combination of the two. If you create a complex spine with many joints for skinning, but control those with a simple stretchy or ribbon spine, and a few controls, you can then control those additionally, by a separate fk-style chain to make for easy arcs. So, going from the top down...fk controls move IK/Stretchy/ribbon spine controls, which manipulate a spine joint hierarchy. Gives you the best of both worlds.

I currently have a pseudo divine spine, from a 3 bone setup using basically midpoint interpolation to control higher detailed bones.

Its the only method i know which allow 90 degrees in pitch, whilst allowing up 180 degrees in roll - something i consider the minimum in spine deformation.

I did use a duriac method to allow twist of -360 to +360 but it doesnt support a high degree of pitch - so more suited for tentacles etc.

For those, like me, who read 'divine spine' and think about funny and glowing things :)
