ArcGIS API for JavaScript 4.0（一）
最近ArcGIS推出了ArcGIS API for JavaScript 4.0，支持无插件3D显示，而且比较Unity和Skyline，速度要快很多，适合在智慧城市中小场景的三维模型应用。下面开始吧！
一、引入样式和js
<link rel="stylesheet" href="https://js.arcgis.com/4.0/esri/css/main.css">
<script src="https://js.arcgis.com/4.0/"></script>
二、导入三个js包
"esri/Map"， "esri/views/SceneView"
require([
"esri/Map",
"esri/views/SceneView",
"dojo/domReady!"
], function (Map, SceneView) {
});
三、创建地图对象
var map = new Map({
basemap: "streets",
ground: "world-elevation"
});
四、创建Scene视图
var view = new SceneView({
container: "viewDiv", //Div的ID
map: map ,
scale: 50000000,
center: [-101.17, 21.78]
});
DOM对象
