Ground polygon is wrong

[hpinkos]

The red is a polygon with height: 0. The purple is where it overlaps with the ground polygon.

var viewer = new Cesium.Viewer('cesiumContainer');

viewer.entities.add({
    polygon : {
        hierarchy : Cesium.Cartesian3.fromDegreesArray([-120.0, 30.0,
                                                        -80.0, 30.0,
                                                        -80.0, 40.0,
                                                        -120.0, 40.0]),
        material : Cesium.Color.BLUE.withAlpha(0.5)
    }
});

viewer.entities.add({
    polygon : {
        hierarchy : Cesium.Cartesian3.fromDegreesArray([-120.0, 30.0,
                                                        -80.0, 30.0,
                                                        -80.0, 40.0,
                                                        -120.0, 40.0]),
        material : Cesium.Color.RED.withAlpha(0.5),
        height: 0
    }
});

viewer.zoomTo(viewer.entities);

@likangning93 I marked this next release but if it doesn't make the February release that's okay. Please look into it ASAP

Is this a rhumb/geodesic conflict?

[hpinkos]

Nope, this is in master

[likangning93]

I think this is a problem with the polygon's bounding rectangle, I have some hunches.

Right, I thought maybe ground polyline was just using a different interoplation, sounds like @likangning93 is on the case! Thanks.
