dabiaoluo / cesium-draw

This is a Vue + Cesium project. Its main functions include plotting and editing marker, polyline and polygon.

Cesium-Draw

基于Vue开发的Cesium基础标绘插件，支持交互式添加BillBoard、Polyline、Polygon、Label和Model

核心功能:

• 鼠标交互绘图
• 对于Billboard、Label、Model支持图标，名称的编辑，图标可以任意扩展.
• 对于Polyline和Polygon支持顶点、颜色等常见图形属性的编辑.
• 支持导入、导出功能
• 可以通过图层管理器管理通过该插件添加的所有图形.

安装

npm i cesium-draw

使用

<template>
    <div>
     <div id='map'></div>
     <cesium-draw ref='drwaManager' :viewer="viewer"></cesium-draw>
    </div>
</template>
<script>
import cesiumDraw from 'cesium-draw'
import 'cesium-draw/dist/theme/default.css'
//import 'cesium-draw/dist/theme/dark.css'
export default{
    name:'your-component',
    data(){
        return {
            viewer:null
        }
    }
    components:{cesiumDraw},
    mounted(){
        this.viewer=new Cesium.Viewer('map')
    }
}
</script>

如果你没有将Cesium Viewer对象保存到Vue data中，你必须显式调用init函数初始化组件。

const viewer=new Cesium.Viewer('map')
this.$refs.drawManager.init(viewer)

怎么扩展标记图标

<cesium-draw ref='drwaManager' :extendMarkerImage="images"></cesium-draw>

data(){
    return{
        images:["./static/images/markers/1.png",
                "./static/images/markers/2.png",
                "./static/images/markers/3.png",
                "./static/images/markers/4.png",
                "./static/images/markers/5.png"
      ]
    }
}

怎么使用模型标记

你必须通过extendMarkerModel属性定义用于标记的模型，才可以使用模型标记。

比如：

<cesium-draw ref='drwaManager' :extendMarkerModel="model"></cesium-draw>

data(){
    return{
        model:[
            { id: "model0", 
            name: "tower", 
            thumb:'thumb.png',
            url: "static/model/Wood_Tower.gltf" },
          { 
              id: "model1", 
              name: "people", 
              url: "static/model/Cesium_Man.gltf" }]
    }
}
