Blender bone structure

Post by jebus » Sat Mar 18, 2006 7:18 am

Hey,
I've been trying to make sense of the way in which blender manages bones, in particular the way in which bone matrices are handled within the program.

The main thing i really want to know is how does blender transform a vertex from within a mesh to its final pose stage?

I've messed around with poseBone.poseMatrix, localMatrix etc in python, but i still havent been able to work it out ...would someone please be able to give me a brief overview?

Any help is much appreciated.

did you see http://blender.org/cms/How_Armatures_work.634.0.html ?

i dont know how exactly the mesh deformation is done, i guess it is pretty readable in the source code.

jebus: do you mean "how does Blender do it within the c source code", or "what steps does a user have to take to get bones to deform a mesh"?

Two very different questions, and it's not clear from your phrasing which you mean.
