I am so confused about definition of these two `EllipsoidGraphics` and `Ellipsoid` I want to add an simple `Ellipsoid` into my map and find its intersection with a ray, I know that I must add an entity to map,I also know that each entity can have `EllipsoidGraphics` property, But I don’t know how to Convert `Ellipsoid` into `EllipsoidGraphics`

Can some one helps me with it? this is a sample code that I use but it does not show any thing

```auto
var elip =new Cesium.Ellipsoid(300000.0, 300000.0,200000.0);

var redSphere = viewer.entities.add({
    name : 'Red sphere with black outline',
    position: Cesium.Cartesian3.fromDegrees(-107.0, 40.0, 300000.0),
    ellipsoid : {
        radii : elip,
        material : Cesium.Color.RED.withAlpha(0.5),
        outline : true,
        outlineColor : Cesium.Color.BLACK
    }
});

```
