I have an application where I need head speed. I am able to get hip speed by making every frame a key frame, copying the frames, and then pasting in Excel. This gives my the hip X Y Z positions in PNUs. Now I need to do the same for the head. The problem is, the head is defined relative to the neck which is defined relative to the chest, which is defined relative to.... etc, until we get down to the hip root.

Is there a way where I can directly get the head XYZ coordinates?

Thank you.
