[Bf-python] Scripts & Armatures

[Gilbert, Joseph T.]

setPose() was a bit of a hack but right now I don't have a replacement for you. :/ 
What this method does is pull the loc/rot/size from the bone and put it in an ipo curve in an Action. It's the only way to set animation frames right now. Because we had no way to get the animation working this method served us well.

The plan however, is to have a 'pose' module which you can use to manipulate the object-level transformation of each bone and from there - you can set the loc/rot/size into an Action. (like you do in the UI with posemode)
The pose code should allow you to manipulate bones with matrices, quat, etc.

The bone.quat stuff was exposed previously but was changed internally with the armature rewrite. Also this property was calculated after the screen updated which caused some weird bugs for people.

The way the editbones work is that you set the head,tail,roll and then parent them to set up the armature. 
Once the armature is setup and parented to an object, you will be able to get the Pose of the object and set the loc/rot/size in each bone in the pose, then send that to an ipo curve.

Great !!! I long to see the result.

I'm updating the BVH2ARM.py script .. the one that
build an armature upon the heap of empty created by
bvh_import.py

By the past .. I used to build armature at rest Pose
by calling setHead() and setTail() functions .. and at
each frame of an animation I was using setQuat() and
setPose() to animate bones ..

According to new Armature API doc, Editbone.matrix is
not writable, and there no longer exist setQuat and
setPose functions ..

So I wonder how I'm going to update BVH2ARM script ..

Keep up the good work .. 
If you have exemple code that shows how it works ..
I'm higly interested in it ..

Keep me posted ..
