Does this mean there is no \theta_y, i.e. changing \theta_y would not make any change on the model?

A bit confused on how this was able to be achieved in the example in class

So the gimbal lock comes up when we compose rotations. That is, our rotation axis got rotated too!

The circled matrix is a rotation (90-theta_x-theta_z degrees clockwise) in 2D

Changing y should make a change. I think it is that you need to change 'much' in y to make a 'small' change.

I understand how gimbal lock can occur on a physical gimbal, where the axes are not locked. But I don't understand how it can happen even if you use global axes?

I feel like the rotation matrices we used are already rotations around the fixed global axis. (correct me if I'm wrong though)

I also wasn't sure why gimbal lock occurs, and why blender (as seen in class) enables it to happen if there is a method to prevent it

Gimbal lock was really confusing
seems we can use quaternion to avoid gimbal locl?
