CZML path line disorted in the distant view

1. A concise explanation of the problem you’re experiencing.

Hi everyone

I use czml path to visualize taxis trail.

It looks great in the near view.

But when I zoom out the trail line will be distorted like this. The L line become a T line

Is it a bug or the a problem of position data?

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

//my CZML code is like this. The coordinates are not the line in picture. But many lines are disorted in my demo.

Any help is appreciated.

Hi there,

I think you are seeing artifacts that arise from using PolylineGlow materials. The issue as been brought up before and is being track on GitHub in issue #4011. I’ve bumped the issue with this report, and if you have the bandwidth, contributing a fix or even tracking down the cause would be greatly appreciated!

Thanks,

Gabby
