Optimization - sign flip near 180deg #149

Closed amymmorton closed 8 months ago

Using extended dataset for the wrist

Frame 25 to 30, yaw flips sign approaching 180 deg yawGimblockQ

Ideally would like to smooth this discontinuity (esp if to be uploaded as sample data)

This is expected behavior since autoscopers backend stores rotations in the range [- $\pi$ , $\pi$ ] ([-180,180]). However, we could update the graph rendering to display in [0, 2 $\pi$ ] ([0,360]).
