Why am I seeing chaotic jumps when extracting ZYX Euler angles near ±90° pitch?
I’m working on a real-time orientation extraction system (ZYX Euler angles) from my omega7 device, and I’m trying to understand why yaw/roll behave chaotically when pitch approaches ±90°, or when I ...

Euler angles continuity ZYX (Yaw Pitch Roll) when pitch crosses ±90
I’m using a Force Dimension Omega.7. From its 3×3 rotation matrix
𝑅
, I extract ZYX Euler angles (Yaw–Pitch–Roll) as:
double yaw= std::atan2(R\[1\]\[0\], R\[0\]\[0\]); // Z
double pitch = std::...
