Example:
// 1. create a rectangle
const rectangle = new Cesium.RectangleGeometry({
ellipsoid : Cesium.Ellipsoid.default,
rectangle : Cesium.Rectangle.fromDegrees(-80.0, 39.0, -74.0, 42.0),
height : 10000.0
});
const geometry = Cesium.RectangleGeometry.createGeometry(rectangle);
// 2. create an extruded rectangle without a top
const rectangle = new Cesium.RectangleGeometry({
ellipsoid : Cesium.Ellipsoid.default,
rectangle : Cesium.Rectangle.fromDegrees(-80.0, 39.0, -74.0, 42.0),
height : 10000.0,
extrudedHeight: 300000
});
const geometry = Cesium.RectangleGeometry.createGeometry(rectangle);
