Introduction

 This is a Cesium development kit that includes functionalities such as layer loading, coordinate conversion, coordinate picking, camera control, measurement, plotting, model loading and manipulation (translation, rotation scaling), 3Dtiles view position adjustment, weather effects (rain, snow, fog), scene rendering with radar scan and information box display capabilities. It also provides features for flow line visualization, lighting effects including dynamic wall and other luminous materials rendering. Additionally it supports Post effects, visibility analysis tools for perspective analysis and slope analysis. Furthermore it offers Inundation analysis as well as volume analysis capabilities and terrain excavation functionality.

Features

• materials
• analysis
• plotting
• dragging
• radar scan
• First-person roaming

1.3 Use case

// test.vue
<template>
  <div id="cesiumContainer" class="map3d-contaner"></div>
</template>
<script>
import { initCesium } from 'cesium_dev_kit'
import { defaultStatic } from '../defaultStaticConf'
export default {
  mounted() {
    this.initMap()
  },
  methods: {
    initMap() {
      const tempData = [
        {
          id: 3,
          name: 'gaodeMap02',
          type: 'UrlTemplateImageryProvider',
          classConfig: {
            url: 'https://webst02.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}',
          },
          interfaceConfig: {},
          offset: '0,0',
          invertswitch: 0,
          filterRGB: '#ffffff',
          showswitch: 1,
          weigh: 13,
          createtime: 1624346908,
          updatetime: 1647395260,
        }
      ]
      const { viewer,material,graphics} =
          new initCesium({
            cesiumGlobal: Cesium,
            containerId: 'cesiumContainer',
            viewerConfig: {
              infoBox: false,
              shouldAnimate: true,
            },
            extraConfig: {
              depthTest: true
            },
            MapImageryList: tempData,
            defaultStatic
          })
    }
  }
}
</script>

2、Import on demand

The import of a single extension class can be tailored to meet specific functional requirements, thereby minimizing code redundancy.

import {Graphics, Material,Primitive,Draw,Analysis,CustomCesiumPlugin,PassEffect,Plugin,ThreeJs} from 'cesium_dev_kit'

2.1 Extension class：

• Graphics:Various graphic operations
• Material: Material manipulation
• Primitive: Cooperate with various primitive operations of shader
• Draw: Various drawing objects
• Analysis: Various analysis objects
• CustomCesiumPlugin: Custom sensor expansion
• PassEffect: Post effect object
• Plugin: Various extension functions
• ThreeJs: Integrate ThreeJS extension objects

2.2 Draw Use case：

// test.vue
<template>
  <div id="cesiumContainer" class="map3d-contaner"></div>
</template>
<script>
import { Draw } from 'cesium_dev_kit'
export default {
  mounted() {
    this.initMap()
  },
  methods: {
    initMap() {
        const tempData = [
        {
          id: 3,
          name: 'gaodeMap02',
          type: 'UrlTemplateImageryProvider',
          classConfig: {
            url: 'https://webst02.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}',
          },
          interfaceConfig: {},
          offset: '0,0',
          invertswitch: 0,
          filterRGB: '#ffffff',
          showswitch: 1,
          weigh: 13,
          createtime: 1624346908,
          updatetime: 1647395260,
        }]

      const drawObj = new Draw({
        cesiumGlobal: Cesium, //Global Cesium object
        containerId: 'cesiumContainer', // Container id
        viewerConfig: { // Same as the official viewer configuration
          infoBox: false,
          shouldAnimate: true,
        },
        extraConfig: {// Other configuration
          logo:true, // Whether to display logo
          depthTest:true // Whether to enable the depth test
        },
        MapImageryList: tempData // Base map configuration
        defaultStatic // default server address and material and other basic information configuration, please refer to src\views\example\defaultStaticConf\index.js
      })

      this.c_viewer = drawObj.viewer
      this.draw = drawObj.draw
      this.draw.setDefSceneConfig()
      this.draw.setBloomLightScene()
      this.load3dTiles(drawObj.viewer)

      this.StraightArrowObj = drawObj.straightArrowObj
      this.AttackArrowObj = drawObj.attackArrowObj
      this.PincerArrowObj = drawObj.pincerArrowObj
    }
  }
}
