""" Imports the bones
About the bone import:
Let m_i be the matrix which does the rotation, scale and translation specified in the m3 file for a given bone i
and b_i the bind matrix (current name: absoluteInverseBoneRestPositions) of that bone i.
Since the matrix m_i is relative to it's parent bone, the absolut transformation done by a bone 2 to a vertex can be calculated with:
F_2 = m_0 * m_1 * m_2 * b_2 where bone 1 is the parent of bone 2 and bone 0 is the parent of bone 1
The bone i in blender should have then the transformation F_i plus maybe a rotation fix r_i to have bones point to each other:
f_2 = F_2 * r_2 = m_0 * m_ 1 * m_2 * b_2 * r_2
In blender however there is the concept of a rest position of an armature.
A bone like it's seen in Blender's edit mode has an absolute transformation matrix
This absolute transformation matrix E_i of a bone i can be used to calculate a relative matrix called e_i:
E_i = E_parent * e_i <=> e_i = E_parent^-1 * E_i
The rotation, location and scale specified in the pose mode can be used to calculate a relative pose matrix p_i for a bone i
For a bone 2 with parent 1, and grandparent 0 the final transformation gets calculated like this:
f_2 = (e_0 * p_0) * (e_1 * p_1) * (e_2 * p_2)
The goal is now to determine p_i so that f_2 is the same as:
f_2 = m_0 * m_1 * m_2 * b_2 * r_2 <=>
f_2 = E * m_0 * E * m_1 * E * m_2 * b_2 * r_2 <=>
f_2 = (e_0 * e_0^-1) * m_0 * (b_0 * r_0 * e_1 * e_1^-1 * r_0^-1 * b_0^-1) * m_1 * (b_1 * r_1 * e_2 * e_2^-1 * r_1^-1 * b_1^-1) * m_2 * b_2 * r_2) <=>
f_2 = e_0 * (e_0^-1 * m_0 * b_0 * r_0) * e_1 * (e_1^-1 * r_0^-1 * b_0^-1 * m_1 * b_1 * r_1) * e_2 * (e_2^-1 * r_1^-1 * b_1^-1 * m_2 * b_2 * r_2)
\------------------------------/ \------------------------------------------/ \-------------------------------------------/
p0 p1 p2
thus:
p_0 = (e_0^-1 * m_0 * b_0 * r_0)
p_1 = (e_1^-1 * r_0^-1 * b_0^-1 * m_1 * b_1 * r_1)
p_2 = (e_2^-1 * r_1^-1 * b_1^-1 * m_2 * b_2 * r_2)
