Question about euler order

[bopeng5221]

I noticed that in bvh_utils.py, there's this line of code. The order is 'YXZ' which is pretty strange to me. Can you explain why you set it to be this order?

It should be because the data is in that order. Y is the main rotation direction pointing upward; putting the more significant rotations first feels more appropriate, and putting X, which rotates less, in the middle also helps avoid Gimbal Lock.
