I am trying to get each tiles’ rectangle and level in current view, and use these information to do some ajax request.

Now I have already got all rectangles through:

```auto
var tileRecangles = [];
var tilesToRender = viewer.scene.globe._surface.tileProvider._tilesToRenderByTextureCount;
    if (Cesium.defined(tilesToRender)) {
        for (var j = 0, len = tilesToRender.length; j < len; j++) {
            var quadTrees = tilesToRender[j];
            if (Cesium.defined(quadTrees)) {
                for (var i = 0; i < quadTrees.length; i++) {
                    tileRecangles.push(quadTrees[i].rectangle);
                }
            }
        }
    }

```

The question is how to get the level for each tiles? [The value in red circles of this screenshot](http://i.stack.imgur.com/gaLSS.png)

Hi Aaron,

In your example, you can get the level from quadTrees[i].level. quadTrees is a bit misnamed, though… those are individual tiles in a quadtree.

You can also simplify it like this:

viewer.scene.globe.\_surface.forEachRenderedTile(function(tile) {

// tile.rectangle and tile.level are available here.

});

Please be aware that you’re depending on implementation details of Cesium with this code, and those details can and will break your code by changing from release to release.
