i have a map and display a two billboards at the same position. The camera is set 200 m above the billboard and heading and pitch are set for a “perpendicular” view (2Pi and -Pi/2).
Changing heading (see screenshot 0, 90, 180) looks like the position is moving - but it is constant.
Has anyone an explanation, why the scene looks like, that the billboard-position is changed.
Thank you for the detailed post! Could you please send a sandcastle demo that showcases this behavior? A demo would help me confirm if this is a bug or a developer error.
I couldn’t send a sandcastle, because the project is confidential. The position of the billboard is constant and I change only the heading of the the camera in a setView - maybe I can produce a sandcastle for this.
I have this behaviour with Cesium World Terrain and ESRI World Imagery.
My Problem is, that the marker has the same position and that I look perpendicular - so I expect that the marker has always the same position in the map !
Is the position of the map correct !
Thank you for sending over the sandcastle demo. This really helps with the debugging process. I just opened up an issue for the most recent bug that you shared. Please feel free to add more details to the issue.
Please check the GitHub issue for an update from another Cesium developer.
The key seems to be setting verticalOrigin: Cesium.VerticalOrigin.CENTER. This is somewhat buried in our documentation but I think it will be helpful for you.
