@ggetz I was able to get this one fixed by using the new TrackingReferenceFrame feature, plus adding a new value TrackingReferenceFrame.ENU (which is the fixed counterpart of AUTO_DETECT). Would you like me to enhance my initial PR #12194 ?
Hi @jfayot! To confirm my understanding: The tracked entity linked above is sometimes moving fast enough that the default camera tracking behavior switches to a VVLH reference frame, very briefly, before switching back to ENU. And this is causing the observed flicker. Is that all correct?
That's it @ggetz ! Trace logs have confirmed this...
Awesome! It sound like your suggestion would work well here then! We would be happy to review a follow-up PR.
@Rubeanster would you mind testing your sandcastle in the PR's #12314 branch?
Just update the last line with:
const entity = dataSource.entities.getById("path");
entity.trackingReferenceFrame = Cesium.TrackingReferenceFrame.ENU;
viewer.trackedEntity = entity;
and tell if it behaves as you would expect.
Just tested the sandcastle off of your branch and it does work as expected now. I do not see any flipping occurring and it looks a lot better!
What happened?
We have been tracking #4647 for a few years now as we thought this was an issue related to ours and it sounded like it was resolved with #12230 last month so we thought we'd give it a try with the latest cesium
1.123
which includes it but our issue still persists.The issue is when we track a path made by CZML the orientation seems to flip causing the screen to jitter (violently at times). Our data can get pretty noisy and I have attached a small sample of it in the sandcastle below.
Orientation at 19:30:48.576:
Orientation at 19:30:48.595:
Alternatively, is there any recommendations to how we could smooth it out so the while tracking the object the camera flip is not as violent?
