效果图

引入相关文件

因为我也是第一次使用，所以我是把插件和源文件都引入了，能使用启动

源文件

下载地址：
http://mars3d.cn/download.html

放入位置

在index.html中引入

	<!--引入cesium基础lib-->
		<link href="/static/Cesium/Widgets/widgets.css" rel="stylesheet" />
		<script src="/static/Cesium/Cesium.js" type="text/javascript"></script>
		<!--引入mars3d库lib-->
		<link href="/static/mars3d-JS/mars3d.css" rel="stylesheet" />
		<script src="/static/mars3d-JS/mars3d.js" type="text/javascript"></script>

引入插件

npm install mars3d --save  

在main.ts里面，加上即可

我是封装的组件，代码的使用和意义 我直接放在备注中

大体布局

父组件

添加地图内部数据和地图外部数据的方法 ，我都是放在上图的moreMethod()方法中一起调用的

子组件

	//需要判断这个图层是否存在，存在就删除之前的图层，然后渲染信的图层页面
