How can I render a polygon the contains the north pole?

[DavidHope]

The app I'm working on requires that we show the "horizon" associated with what an object (say a satellite) in space can see, based on its altitude and FOV. I typically can render this with no problem, except when the horizon circle contains the north pole, then all sorts of weirdness can happen. Here is an example:

On both the sceneview, the black outline correctly denotes what I expect to see, but the polygon doesn't fill  correctly.

On the mapview, I expect to see something that looks like a sine wave filled in from the top.

In neither case did I get what I expected.

I've attached the code that generates this image. Run it and click the "Large Circle Issue" button.

Thanks,

David

Hi,

We did a lot of work to improve this for the recent v100.2 release, although I think we still have some more work to do here to get it right in all scenarios. 

Please download the latest Visual Studio extension from ArcGIS for Developers or update your NuGet packages via the NuGet package manager.

Cheers

Mike
