How to integrate into your existing projects

1. Install the Mars3D dependency package

   npm install mars3d   //  or yarn add mars3d

2. Copy files

   Scene profile：public\config\config.json

   Component definition file：src\components\mars3d\Map.vue

1. configuration vue.config.js

The current warehouse is based on vueCli 4.x

// vue.config.js  
let cesiumSourcePath = 'node_modules/mars3d-cesium/Build/Cesium/' //cesium库目录
let cesiumRunPath = config.output.publicPath || './cesium/' //cesium运行时主目录
let plugins = [
  //标识cesium资源所在的主目录，cesium内部资源加载、多线程等处理时需要用到
  new webpack.DefinePlugin({
    CESIUM_BASE_URL: JSON.stringify(cesiumRunPath)
  }),
  //cesium相关资源目录需要拷贝到系统目录下面
  new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Workers'), to: path.join(cesiumRunPath, 'Workers') }]),
  new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Assets'), to: path.join(cesiumRunPath, 'Assets') }]),
  new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'ThirdParty'), to: path.join(cesiumRunPath, 'ThirdParty') }]),
  new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Widgets'), to: path.join(cesiumRunPath, 'Widgets') }])
]

For vueCli 3.x, configure plugins as follows

// vue.config.js
const CopyWebpackPlugin = require('copy-webpack-plugin') 

module.exports = {
  //Other configurations have been ignored
  configureWebpack: config => {
    let cesiumSourcePath = 'node_modules/mars3d-cesium/Build/Cesium/' //cesium库目录
    let cesiumRunPath = config.output.publicPath || './cesium/' //cesium运行时主目录
    let plugins = [
      //标识cesium资源所在的主目录，cesium内部资源加载、多线程等处理时需要用到
      new webpack.DefinePlugin({
        CESIUM_BASE_URL: JSON.stringify(cesiumRunPath)
      }),
      //cesium相关资源目录需要拷贝到系统目录下面
      new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Workers'), to: path.join(config.output.path,cesiumRunPath, 'Workers') }]),
      new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Assets'), to: path.join(config.output.path,cesiumRunPath, 'Assets') }]),
      new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'ThirdParty'), to: path.join(config.output.path,cesiumRunPath, 'ThirdParty') }]),
      new CopyWebpackPlugin([{ from: path.join(cesiumSourcePath, 'Widgets'), to: path.join(config.output.path,cesiumRunPath, 'Widgets') }])
    ]

    return {
      plugins: plugins
    }
  },
}

When vue.config.js is not configured, the cesium Library of CDN is imported directly

If you encounter various strange problems that cannot be solved during the integration in step 3 above, most of them are the configuration problems of vue.config. Modify the following comments in public\index.html

<link href="https://unpkg.com/mars3d-cesium/Build/Cesium/Widgets/widgets.css" rel="stylesheet"   type="text/css" />
<script src="https://unpkg.com/mars3d-cesium/Build/Cesium/Cesium.js"  type="text/javascript"></script>
<script src="https://unpkg.com/@turf/turf/turf.min.js" type="text/javascript" ></script>

When vue.config.js is not configured, the external cesium library is imported directly

If you encounter various strange problems that cannot be solved during the integration in step 3 above, most of them are the configuration problems of vue.config.

The Cesium library introduced by Script can be used directly in HTML without modifying vue.config

Copy cesium from the SDK downloaded from the official website, put it underpublic\lib\Cesium\,and cancel the following comments inpublic\index.html

<script type="text/javascript" >
  window.CESIUM_BASE_URL ="<%= BASE_URL %>lib/Cesium/"
</script>
<link rel="stylesheet" href="<%= BASE_URL %>lib/Cesium/Widgets/widgets.css">
<script type="text/javascript" src="<%= BASE_URL %>lib/Cesium/Cesium.js"></script>

1. Create the earth

   Refer to the src\views\Index.vue file to introduce the Map component and construct the creation of the earth, focusing on the following code

<Map :url="configUrl" @onload="onMapload" />

import Map from '../components/mars3d/Map.vue'

1. Common problem

   When running an error, please check whether there is any conflict between the related versions, such as webpack 4.43.0 and copy-webpack-plugin 7.0.0

   1. Check the compatibility between webpack and copy-webpack-plugin versions
   2. Check whether webpack and copy-webpack-plugin are compatible with Node and NPM versions

What is Mars3D

Mars3D platform is Mars technology a 3D client development platform based on WebGL technology, which is based on Cesium optimization and B / S architecture design,The lightweight and efficient GIS development platform supporting multi industry expansion can run efficiently in the browser without installation and plug-ins, and can quickly access and use a variety of GIS data and three-dimensional models, present the visualization of three-dimensional space, and complete the flexible application of the platform in different industries.

Mars3d platform can be used to build 3D GIS applications without plug-ins, across operating systems and across browsers. The platform uses WebGL for hardware accelerated graphics, and realizes real dynamic big data 3D visualization across platforms and browsers. The Mars3D product can quickly realize beautiful and smooth 3D map presentation and spatial analysis on browsers and mobile terminals.
