Camera go underground after camera.flyto() complete

CesiumJS
1

Hi everyone

I use camera.flyTo(), and then tilt the camera, the view goes underground. (even in the sandcastle Camera example, I met the same problem)

If I don’t use flyTo(), (e.g., zoom in manually or use setView), I never go underground.

This may be a bug. And I wonder how to fix it.

My Cesium is 1.36. The figure below is the camera underground with 3d-tiles model.

Any help appreciated.

Thanks

Chris

Thanks Gabby

In the issue you provided, the camera flyTo underground directly when flyTo() runs.

But in my case, every time after flyTo() runs, I can tilt the camera into underground.

I hope I describe the problem clearly.

Got it, thanks for the clarification Chris.

Can you provide a code sample, preferably a sandcastle example? This will help track down the root of the problem, and I can open a GitHub issue if this is a whole new bug.

Thanks!

Hi Gabby

You can just use the Camera demo in Sandcastile.

I run the demo, click any Fly to option, and then tilt the camera.

Thanks

Hi Chris,

I don’t think I duplicate this. I’ve try every flyto option and then I rotate the view. I can’t get the camera to go underground.

Thanks,

Thanks Gabby

I think it may be the slow internet speed for loading the terrain that cause the camera go underground.

I will try to figure it out later

OK, let us know if you can provide any more details so we can reproduce this!
