Not enough ellipse edges, can't add more vertices to ellipse.

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

A need a more accurate ellipse in regard to it's edge points. Needs to be smoother.

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

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Currently ellipses are made with very few points, creating jagged sharp edges, I need it to be made with 1000 so that it's more accurate.
I haven't found a way to do this. My only other option is to make a polyline that is made to look like an ellipse, it'll take a lot more work though.
Thanks for all the help you can give.

4. The Cesium version you're using, your operating system and browser.

The granularity parameter lets you control this. So this ellipse will have 10x as many points as the default:

var redEllipse = viewer.entities.add({

position: Cesium.Cartesian3.fromDegrees(-103.0, 40.0),

name : ‘Red ellipse on surface’,

ellipse : {

semiMinorAxis : 250000.0,

semiMajorAxis : 400000.0,

material : Cesium.Color.RED.withAlpha(0.5),

granularity: Cesium.Math.RADIANS_PER_DEGREE * 0.1

}

});
