I’m trying to use the CZML Path object to leave a trail behind a visualisation of some tracking data. When I just track the object and have it rotate based on bearing information - this works fine and performance is fantastic.
However, adding a path immediately yields two problems:
(1) The path doesn’t display in 2D view (only in 2.5 and 3D).
(2) As soon as I add a path, the performance of Cesium as a whole becomes choppy (panning + zooming etc).
Are these expected behaviours? I know polyline rendering wasn’t very efficient in the past but I thought that that had been improved in newer releases?
Does anyone have any suggestion on a faster, easy way to render trails in CZML.
I’ve attached an example CZML file illustrating the problem. If there’s any more information I can provide that can help, please let me know.
