how to get current tiles' level and scale?

hello guys,who can tell me how to get current tiles’ level and the scale? thanks very much !


Sorry, I can’t answer your question, just a remark. When Cesium works in 3D mode, tiles of some different levels are represented on the screen simultaneously.

You can run this in the SandCastle.

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var layers = viewer.imageryLayers;

layers.addImageryProvider(new Cesium.TileCoordinatesImageryProvider());
