As an example of what I meant to say, take one of Serge's bandana ties. According to the way my script is interpreting the Section 2 data (which appears to be kinda close, but not quite, to the right way to do it), the rotation data for those vertices comes out to be (-82.5, 89.9, 6.2). A set of rotation angles with only one nonzero value, e.g. (-82.5, 0, 0), would correspond to a rotation around the axis corresponding to the nonzero value by the amount of the value, e.g. rotate -82.5 degrees around the x-axis. The problem is that rotating around one axis causes the other two axes to move, and so the order of rotations matters.
