Rotation problem raised when tilt > 90 degree

MarkLam1 — Mon, 05 Sep 2016 09:15:33 GMT

Hi all,

I am using ArcGIS Javascript 4.0 API and want to manually write the rotate function. The function simply add camera.heading by 5 degree after cloning the camera out and then assign it back to the original view.camera. The function is triggered by pressing a button. The rotation runs smoothly when tilt is < 90 degree. However, when it is > 90 degree, something strange happen. The heading will dramatically increase and tilt will go back to < 90 degree. May I know whether it is a bug or configuration issue?

Attached please find the excel for the testing.

Thanks a lot!

Mark... are you doing this for arcmap or arcgis pro? or some other software? On GeoNet, the only hits with javascript and camera as keywords are returning nonsense results and no paired combinations. Either the deployment isn't for with arcmap/pro but elsewhere, and grabbing that help file would be useful. Is it this documentation ArcGIS API for JavaScript | ArcGIS for Developers because there is a link which suggests the camera is limited to 0-90 unless I am miss reading it Camera | API Reference | ArcGIS API for JavaScript 4.0

Hi Dan,

I am writing a web application by using ArcGIS Javascript 4.0 API. Actually I have posted another question for getting a tilt which is larger than 90 degree when using WebScene. And it has been solved by setting SceneView | API Reference | ArcGIS API for JavaScript 4.0 . However, the problem mentioned in this post raised after setting the tilt > 90 degree.

Below is the link for the relevant post:

Why WebScene can tilt larger than 90 degree but Javascript 4.0 API cannot?

I guess I misunderstood, I thought you were referring to the camera tilt constraints as cited in my 2nd link.

May I know if this is a bug or?

I haven't seen any reference other than the links I sent. You should check internally to see if this is a bug or an interpretation issue.
