Render poles properly on globe #3727

Open markschlosseratbentley opened 2 years ago

The poles do not render properly in the globe. See screenshot below. They used to render properly, but no longer do - these need to get implemented properly / fixed.

It has recently been observed that this problem goes away if terrain is enabled.

That is because Cesium terrain tiles use a geodetic tiling scheme instead of the spherical mercator scheme used by most web map tiles. The latter projects to infinity at the poles.

They used to render properly

It would be extremely helpful to know when they stopped rendering properly, to identify why.
