I trried FollowCamera which comes close to what I need, although it doesn’t roll.
BUT … FollowCamera introduces significant jitter. Others observed that, too: How to remove Camera Movement Jitter
This is particularly strange bc. I cannot reproduce it in playground. OTOH it remains in my flightsimulator even when I reduce it to the bare minimum of a freefalling box. The jitter reduces the smaller I make the cameraAcceleration parameter. It also seems to vary between browsers and machines. It does not happen with any other camera implementation.
Anybody else observed similar effects?
