Flyto or zoomto to an entity or entities

[CMCDragonkai]

On cesium you can normally add an entity and fly to that entity:

            var wyoming = viewer.entities.add({
                name: 'Wyoming',
                // polygon :: Cesium.PolygonGraphics
                polygon: {
                    // polygon longitude and latitude (not totally accurate)
                    hierarchy: Cesium.Cartesian3.fromDegreesArray([
                        -109.080842, 45.002073,
                        -105.91517,  45.002073,
                        -104.058488, 44.996596,
                        -104.053011, 43.002989,
                        -104.053011, 41.003906,
                        -105.728954, 40.998429,
                        -107.919731, 41.003906,
                        -109.04798,  40.998429,
                        -111.047063, 40.998429,
                        -111.047063, 42.000709,
                        -111.047063, 44.476286,
                        -111.05254,  45.002073
                    ]),
                    material: Cesium.Color.RED.withAlpha(0.5)
                }
            });

            viewer.flyTo(wyoming).then(function(result){
                if (result) {
                    viewer.selectedEntity = wyoming;
                }
            });

I just tried this with an entity I added via ob = v.dataSources.add() but I wasn't able run v.camera.flyTo(ob), it didn't fly anywhere.

How can this be done? Also I'm a bit confused as to how Cesium's Javascript API maps to the Python object API, some things are placed in different areas.

Furthermore, how do you set the default position of the camera? This didn't work: http://stackoverflow.com/questions/28709007/how-to-set-the-default-view-location-cesium-1-6

Thx for the report. Because simple JavaScript call v.camera.flyTo(v.dataSources) doesn't work, current impl needs to be fixed. Will consider better soln.

This might help someone since I also had trouble using zoomTo on an entity that had just been added. https://cesium.com/docs/cesiumjs-ref-doc/Rectangle.html#.fromCartesianArray

    const arrayOfPositions = /* create array of Cesium.Cartesian3 here */;
    const destination = Cesium.Rectangle.fromCartesianArray(arrayOfPositions);
    this.viewer.camera.setView({
      destination,
    });
    this.viewer.camera.zoomOut(); // maybe not needed but adds a helpful buffer for my purposes
