There are 19 bones per human body.


The index array specifies the hierarchy of the bones (basically a generic tree).


there are 19 bones per human body
The translation array specifies the translation of every bone with respect to its parent.
:Every translation is specified in the respective parent's local frame of coordinates.


when composing a body of them, one at first rotates a particular body part in the order: z, y, x; then translates the bodypart to the vector from the TRTA array, and then applies parent body part's transformation to it
Rotations are also specified in the local frame of every bone's respective parent.
:The rotation is either a quaternion or a triplet of heading/pitch/banking angles.
::In the latter case, "heading" is around x, "pitch" about y, and "banking" about z.




the rotation values are: (took it from OniBrowser and modified some angles)
