Creating a polygon also adds an artifact that moves around when you pan or zoom. #12246

Open sgomon12 opened 1 week ago

sgomon12 commented 1 week ago

What happened?

I tried to create a thick line path with an arc, but when I add the last point, it also creates an artifact next to it. When you pan or zoom, the artifact moves around, but the thick line path stays fixed like it should. Also, this only happens when I add the last point to complete the path. If I don't add the last point, there is no artifact.

artifact

Reproduction steps

  1. Create a polygon with the specific points in the Sandcastle example to see the artifact
  2. Comment out the last point to remove the artifact

Thanks for the report @sgomon12.

There's a chance this is a similar indexing issue to https://github.com/CesiumGS/cesium/issues/12136.

Hi, Thank you for the reply. I don’t think this is the case. The image below shows the polygon created without the last point. The last point is shown in red with the yellow lines outlining the final area to be filled.

@.***

So, where the last point lies looks like a valid position.

Let me know if you think this this problem is still related to #12136.

Thank you, Steve
