I more detailed explained our problem, why we started smoothing deviceOrientation camera here: Fixing DeviceOrientationCamera noize for android devices
We almost found out perfect solution, but we only have problem smoothing, when alpha value goes from 0 to 360 and from 360 to 0. We cant find a solution. It is really hard to average Quaternions. When alpha goes from 0->360 (x,y,-z,w) → (-x,y,-z,-w) and the other way around, but this just doesn’t smooth nice enough
Does anyone has a mathematical solution how to solve this problem in the code?
