Hello there,

Many thanks for making this awesome package!

I have noticed that some country polygons from the Natural Earth data don't render correctly. This can be seen by removing the wireframe: true from this line in the Countries example and rotating/zooming to Iceland:

You can see that the triangles aren't correct. Now, I notice that raising the curvatureResolution parameter in the THREE.ConicPolygonGeometry constructor to 5 seems to fix that:

But this breaks other country polygons, such as the nearby Greenland.

Is it possible to configure the ConicPolygonGeometry to get the polygons perfect?

Cheers

Seb

The conic-polygon-geometry only uses border coords, it works fine for small regions. But for big regions, it makes large flat areas which will be blocked by the sphere surface:

with 0 altitude, only borders are visible for most regions

with 0.1 altitude, more visible regions, but still holes for big countries

The idea would be adding vertices in the middle of regions, especially for big regions, then bend around the globe, finally something like:

It will be very nice if the vertices/triangulated map can be done automatically!

I'm experiencing this bug a couple repos up from here, but I'm pretty sure its a bug since the other repos just call this one.

I'm getting this GEOJSON feature from uber's h3ToGeoJson function.
when I plug it into geojson.io it appears normally.
however when I put it on the globe it renders the polygon feature as everything except the hexagon.

Let me know if there is a fix I can do to transform the hexagon, or a setting in the three conic polygon geometry to fix this
