CZML-Corridor and CZML-Polyline behavior

CesiumJS

Hi there,

I have a great circle as a polyline and a corridor with the same coordinates. The polyline looks good, but the corridor moves around the polyline. I don’t understand why I have such a different behavior of corridor and polyline. Look at France.

Thank you for your help,

Jörg

Here another striped example:
Aleisa 5-corridor matches perfect, Aleisa 6-corridor not at all.

No feedback so far. Should I open an issue on github?

Hi @leylines ,
Thank you for your post and apologies you did not receive a response yet. I think it would be fine to open an issue to investigate this as a possible bug. When you do so, please link back to this forums thread so we can make sure any resolution gets updated here as well.

Thanks,
Luke

Hi @leylines, I updated the issue with my own quick check, and some possibly related issues .

It seems as though the problem could be in CorridorGeometry. Unfortunately I didn’t see anything obvious on first glance. Would you be able to step through and see what it is doing with your example?
