hi, I am looking for some papers or links on bone animation and facial expression, but I have no idea where to find these resources. Can anyone help me

I finish my human body enginer, and i don''t copy some alghoritm, because there are many, and you don''t find a unique bone/facial animation... You can find some information about facial in gamasutra (links in gamedev mainpage!).

Problem i found :
1)Kind of model-format, now i create a new type of model, derived about .x format.
2)Geometric blend and/or bone animation and/or frame model??.. Geometric blend work perfectly with 3dstudio, but it is a cpu-expensive.
3)Use of keyframe (animation).
4)make a library of object/animation

Here''s a really good link with a PDF document,executable and source code.I''m assuming you want to use bones to animate a deformable mesh,no? Check it out.It might help.
