Try adding this after your first block of code above:
var scene = map.scene;
var ellipsoid = Cesium.Ellipsoid.WGS84;
var west = Cesium.Math.toRadians(-77.0);
var south = Cesium.Math.toRadians(38.0);
var east = Cesium.Math.toRadians(-72.0);
var north = Cesium.Math.toRadians(42.0);
var extent = new Cesium.Rectangle(west, south, east, north);
scene.camera.viewRectangle(extent, ellipsoid);
More examples are available in our Camera Demo.
EDIT (May 2014): Due to Cesium API changes, .getCamera()
is renamed .camera
, the camera's .controller
was removed and rolled into the camera itself, and Extent
is renamed to Rectangle
. The above code now reflects the new API. For a complete list of breaking changes, see CHANGES.md.
