Alexander you could check this paper out that improves upon our
existing bone heat weighting method. Very useful!

- The skeleton mentioned is only the deforming joints right? or does it
include (for example) IK/FK switching, controls, etc. ?
If it is adding joints to the mesh via topology, I'm not sure that it is
more than limited usefulness; agreeing with Nathan here. This might be
an easy problem to solve,

Can this method be used for approximate convex decomposition of
characters (or even arbitrary complex models)? It would be useful too.

Eh... I think I may be a bit confused. The proposal is about
automatically generating skeletons for an arbitrary model, but it
sounds like the workflow you outlined doesn't automate that step at
all. What you've outlined is still cool, but it sounds orthogonal to
The method is fully automatic.
The method generates a new skeleton from a mesh of polygons.
The method links the skeleton and mesh.
The method does not use any sample skeleton.
The proposed method provides only the skeleton, and the artist will have to
animate the skeleton.

It's a very advanced method :-)

How do you deal with cases for example linking the hip to the ankle where

Hello, Thank you all for your comments.
First of all I want to make some clarifications::
- This method does not use any template or skeleton model.
- This method ensures that the skeleton generated depends only on the
features of the mesh (size, shape, segments, curvature, etc).

The character animation is generally done with skeletons that control each
joint in the character which drastically simplifies the animation process.

Alexander,
First, I must make a disclaimer. I am NOT a Blender developer, so my
opinion really doesn't matter. Take what I say with a grain of salt.
That said, time to get to business. Speaking as a Blender user, I
would love to have this feature. It would definitely help me.
We have had a number of automated armature tools in the past that
never really delivered something usable in production. It is my
opinion that rigging has a long way to go before it can be automated.
The creation and positioning of bones is not only critical to a good
rig but also not that hard to

For reference, Martin Poirier did a project to implement an automatic
skeleton generator. The code for that is actually still there
(editors/armature/reeb.c) but disabled and never integrated into the
2.5 UI.
