Sometimes we need to run Cesium without the internet connection. Usually, all Cesium data such as imagery, the terrain is streamed from several remote servers. How can I get Cesium data? Please use this, CesiumDataCrawl.
var downLoader = require('./../Downloader');
var BingMapsImageDownloaderUtil = require('./../BingMapsImageDownloaderUtil');
var bingMapsImageUtil = new BingMapsImageDownloaderUtil({});
var savePath =__dirname + "/../CesiumData/Image/BingMaps";
var startLevel = 1; var endLevel = 5;
var requestRect = require('./../RequestRect/WorldWebMercatorRect'); requestRect = requestRect.RequestRect();
var downloadInfoList = bingMapsImageUtil.prepareDownloadInfoList(savePath, startLevel, endLevel, requestRect.left, requestRect.bottom, requestRect.width, requestRect.height);
var timeout = 1000; // 1s
downLoader.recursivelyDownload(downloadInfoList, downloadInfoList.length, timeout);
