Standard pose skeleton

[gilmartinspinheiro]

Hello!

First of all, thank you for your great work :)

I am struggling to understand the creation of the standard skeleton here

pose3d2bvh/bvh/body25hand21.py

Line 28 in 2022457

self.con2dir = {

More specifically, I am struggling to understand what is the thought process for the hands.

For example, why is (7, 30): [3, 0, 1] picked here?

pose3d2bvh/bvh/body25hand21.py

Line 79 in 2022457

(4, 51): [-3, 0, 1], # w->index_finger

Hope you can help, thank you in advance!
