1、上一节讲了arcgis js入门与提高（一）加载二维地图arcgis js（一）显示二维地图_郝大大的博客-CSDN博客，本节继续讲如何加载三维地图，与3.x版本不同，ArcGIS API for JavaScript 3.x版本地图都是显示在map中，从4.x版本之后地图的显示全部放在view上，二维的叫mapview，三维的叫sceneview，因此三维场景加载方式如下：
<html><head><meta charset="utf-8" /><meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no" /><title>3D map</title><style>html,body,#viewDiv {padding: 0;margin: 0;height: 100%;width: 100%;}</style><link rel="stylesheet" href="https://js.arcgis.com/4.20/esri/themes/light/main.css" /><script src="https://js.arcgis.com/4.20/"></script><script>require(["esri/Map", "esri/views/SceneView"], (Map, SceneView) => {const map = new Map({basemap: "topo-vector",ground: "world-elevation"});const view = new SceneView({container: "viewDiv",map: map,scale: 50000000,center: [-101.17, 21.78]});});</script>
</head><body><div id="viewDiv"></div>
</body></html>2、效果如下：
