I am having trouble understanding why Euler Angles are used to rotate objects at all. Why parent the axes of rotations and have them depend on each other and change orientation when the parent changes?
If I want to rotate an object, can't I just use the fixed global coordinate system to do this? In other words, do they solve a real problem, make rotations easier?
This is essentially asking what's the pros/cons of intrinsic vs extrinsic rotations?
