描述点

viewer.entities.add({
    name: name,
    position: new Cesium.Cartesian3.fromDegrees(lon, lat, h),
    // 广告牌
    billboard: new Cesium.BillboardGraphics({
      image: icon || "images/shuniu.png",
      horizontalOrigin: Cesium.HorizontalOrigin.CENTER,
      verticalOrigin: Cesium.VerticalOrigin.BOTTOM,
      alignedAxis: Cesium.Cartesian3.ZERO,
      disableDepthTestDistance: Number.POSITIVE_INFINITY,
      // 能够显示的间隔
      distanceDisplayCondition: new Cesium.DistanceDisplayCondition(
        0,
        height
      ),
    }),
 });

描述线

// positions 是笛卡尔坐标系 x y z
let polyCenter = Cesium.BoundingSphere.fromPoints(positions).center;
    polyCenter = Cesium.Ellipsoid.WGS84.scaleToGeodeticSurface(polyCenter);
viewer.entities.add({
  show: true,
  position: polyCenter, // 为了找到线的中心点，不须要能够不必写
  name: row.PlacemarkName,
  polyline: {
    positions,
    width: row.LineWidth || 2,
    material: new Cesium.Color.fromCssColorString(row.LineColor || 'red'),
    clampToGround: true,
    show: true,
    distanceDisplayCondition: new Cesium.DistanceDisplayCondition(
      0,
      row.LineShowHeight
    ),
  }
})

增加闪光尾迹线

首先得先全局开启闪耀成果

viewer.scene.bloomEffect.show = true;
viewer.scene.hdrEnabled = true;
viewer.scene.bloomEffect.bloomIntensity = 1;

而后实现尾迹线

viewer.entities.add({
    // 尾迹线
    polyline: {
      positions,
      width: row.LineWidth || 2, // 线的宽度，像素为单位
      material: new Cesium.PolylineTrailMaterialProperty({
        // 尾迹线材质  值越大光越闪耀 0- 1 属于失常 1 以上闪耀成果
        color: new Cesium.Color(
          1.00392156862745098,
          3.8784313725490196,
          0.3176470588235294,
          1
        ),
        trailLength: 0.4,
        period: 10,
      }),
      distanceDisplayCondition: new Cesium.DistanceDisplayCondition(
        0,
        row.LineShowHeight
      ),
    },
    ClampToGround: true,
 });

波纹雷达圈

首先得扩大 cesium 办法 存为 CircleWaveMaterialProperty.js

export class CircleWaveMaterialProperty {constructor(options) {options = Cesium.defaultValue(options, Cesium.defaultValue.EMPTY_OBJECT);

    this._definitionChanged = new Cesium.Event();

    this._color = undefined;

    this.color = options.color;

    this.duration = Cesium.defaultValue(options.duration, 1e3);

    this.count = Cesium.defaultValue(options.count, 2);

    if (this.count <= 0) this.count = 1;

    this.gradient = Cesium.defaultValue(options.gradient, 0.1);

    if (this.gradient < 0) this.gradient = 0;

    else if (this.gradient > 1) this.gradient = 1;

    this._time = performance.now();}

}

Object.defineProperties(CircleWaveMaterialProperty.prototype, {
  isConstant: {get: function () {return false;}

  },

  definitionChanged: {get: function () {return this._definitionChanged;}

  },

  color: Cesium.createPropertyDescriptor('color')

});

CircleWaveMaterialProperty.prototype.getType = function (time) {return Cesium.Material.CircleWaveMaterialType;}

CircleWaveMaterialProperty.prototype.getValue = function (time, result) {if (!Cesium.defined(result)) {result = {};

  }

  result.color = Cesium.Property.getValueOrClonedDefault(this._color, time, Cesium.Color.WHITE, result.color);

  result.time = (performance.now() - this._time) / this.duration;

  result.count = this.count;

  result.gradient = 1 + 10 * (1 - this.gradient);

  return result;

}

CircleWaveMaterialProperty.prototype.equals = function (other) {
  return this === other ||

    (other instanceof CircleWaveMaterialProperty &&

      Cesium.Property.equals(this._color, other._color))

}

Cesium.Material.CircleWaveMaterialType = 'CircleWaveMaterial';

});

Cesium.CircleWaveMaterialProperty = CircleWaveMaterialProperty;

调用前须要存在此办法，也就是得全局调用一次，让 cesium 领有雷达圈得类

require("./CircleWaveMaterialProperty");

调用

viewer.entities.add({position: new Cesium.Cartesian3.fromDegrees(lon, lat, h),
    ellipse: {
      height: 1,
      semiMinorAxis: 1000,
      semiMajorAxis: 1000,
      material: new Cesium.CircleWaveMaterialProperty({
        duration: 2e3,
        gradient: 0.5,
        color: new Cesium.Color(1.0, 0.0, 0.0, 1.0),
        count: 2,
      }),
      disableDepthTestDistance: Number.POSITIVE_INFINITY,
      distanceDisplayCondition: new Cesium.DistanceDisplayCondition(
        0,
        height
      ),
    },
    clampToGround: true,
    billboard: {image: this.renderText(name),
      horizontalOrigin: Cesium.HorizontalOrigin.CENTER,
      verticalOrigin: Cesium.VerticalOrigin.BOTTOM,
      alignedAxis: Cesium.Cartesian3.ZERO,
      disableDepthTestDistance: Number.POSITIVE_INFINITY,
      pixelOffset: new Cesium.Cartesian2(0, -40),
      distanceDisplayCondition: new Cesium.DistanceDisplayCondition(
        0,
        height
      ),
    },
});

点击某个图层呈现对应弹窗

留神: 因为是监听每一帧的事件, 弹窗太多 cesium 必会卡顿!

// 创立弹窗对象的办法
const Popup = function (info) {this.constructor(info);
};
Popup.prototype.id = 0;
Popup.prototype.constructor = function (info) {
  const _this = this;
  _this.viewer = info.viewer;// 弹窗创立的 viewer
  _this.geometry = info.geometry;// 弹窗挂载的地位
  _this.id = "popup_" + _this.__proto__.id++;
  _this.html = info.html

  const dom = document.createElement('div');
  dom.className = 'bx-popup-ctn';
  dom.id = _this.id;

  _this.ctn = dom;

  _this.viewer.container.appendChild(_this.ctn);

  _this.ctn.insertAdjacentHTML('beforeend', _this.createHtml(info.title, info.data));

  _this.render(_this.geometry);
  _this.viewer.scene.postRender.addEventListener(_this.eventListener, _this)
}

Popup.prototype.eventListener = function () {this.render.call(this, this.geometry);
}

// 弹窗的内容
Popup.prototype.createHtml = function (title, data) {
  window.pop = this
  return ` <div class="cesium-pupop-title">
    <h1 class="title">${title}</h1>
    <span class="iconfont icon-cha1" style="position: absolute;color: #00fbfb;top: 33px;right: 30px;cursor:pointer;" onclick="pop.close()"></span>
    ${data.length > 0 ? data.map(v => `<div class="cesium-row"><span>${v.name}:</span> <span>${v.value}</span></div>`).join('') :'<div class="cesium-row" style="color: #fff;text-align: center;height: 200px;line-height: 200px;"> 暂无属性 </div>'}
  </div>`
}

// 重点是实时刷新
Popup.prototype.render = function (geometry) {
  var _this = this;
  var position = Cesium.SceneTransforms.wgs84ToWindowCoordinates(_this.viewer.scene, geometry)
  _this.ctn.style.left = `${position.x - Math.floor(_this.ctn.offsetWidth / 2)}px`
  _this.ctn.style.top = `${position.y - _this.ctn.offsetHeight - 10}px`
}
// 敞开弹窗按钮
Popup.prototype.close = function () {
  var _this = this;
  _this.ctn.remove();
  // _this.viewer.clock.onTick.removeEventListener(_this.eventListener);
  _this.viewer.scene.postRender.removeEventListener(_this.eventListener, _this)
}

export default Popup;

调用

new CesiumPopup({
    viewer: viewer,
    geometry: polyCenter, // 这个坐标是世界坐标也就是笛卡尔坐标!
    title: entity._name,
    data: ddd
});

拿到图层后如何设置图层高度

const osgbLayer = viewer.scene.addS3MTilesLayerByScp(url, { name: row})
Cesium.when(osgbLayer, function (row) {if (node.data.DisplayHeight) {
   // 设置海拔高度
    row._style3D.bottomAltitude = node.data.DisplayHeight
  }
})

拿到图层后如何设置图层可见高度

const osgbLayer = viewer.scene.addS3MTilesLayerByScp(url, { name: row})
Cesium.when(osgbLayer, function (row) {
  // 可见海拔高度设置
  // row.maxVisibleAltitude = node.data.MaxDisplayHeight
  
  // 设置相机和图层的可见间隔
  row.visibleDistanceMax = layer.DisplayHeight || 100000;
})

设置地形

viewer.terrainProvider = terrainProvider = new Cesium.CesiumTerrainProvider({
    // url 形如:  http://172.18.1.106:8090/iserver/services/3D-SuiZhouDianChang/rest/realspace/datas/ 图层名称
    url: url + '/datas/' + name,
    isSct: true
  })

加载影像

viewer.imageryLayers.addImageryProvider(new Cesium.UrlTemplateImageryProvider({
    url: _url,
    tilingScheme: new Cesium.WebMercatorTilingScheme(),
    subdomains: '1234',
  }));

加载服务器贴图

viewer.imageryLayers.addImageryProvider(new Cesium.SuperMapImageryProvider({url: '/iserver/services/3D-QuanMuTangChuSheFaBu/rest/realspace/datas/xxx 影像缓存',}));

获取实体属性

首先拿到选中的图层及其 SMID

// 获取到选中的 layer
const selectedLayer = scene.layers.getSelectedLayer();
if (selectedLayer) {var selectedSmid = parseInt(selectedLayer.getSelection());
    // 获得超图属性
    if(callback){
      // 拿到 layer 和 smid 就行了
      callback(selectedLayer, selectedSmid)
    }
}

依据 SMID 查问属性

doSqlQuery(sqlStr, dataSerice, dataset, datasource) {
  const _this = this;
  const sqlParameter = {"datasetNames": [`${datasource}:${dataset}`],
    getFeatureMode: "SQL",
    queryParameter: {attributeFilter: sqlStr}
  };
  const url = `/iserver/services/${dataSerice}/data/featureResults.json?returnContent=true&token=${eval(localStorage.getItem('TOKEN_ISERVER'))}`
  const queryData = JSON.stringify(sqlParameter);

  const IGNOREFIELD = JSON.parse(localStorage.getItem('IGNOREFIELD'))

  _this.loading = true
  $.ajax({
    type: "post",
    url: url,
    data: queryData,
    success: function (result) {if (result.features && result.features.length > 0) {const data = result.features[0]
        const fieldNames = data.fieldNames
        const fieldValues = data.fieldValues
        _this.moduleListData = []
        fieldNames.forEach((row, i) => {if (IGNOREFIELD.indexOf(row) !== -1) return
          _this.moduleListData.push({
            Name: row,
            Value: fieldValues[i]
          })
        })
      } else {_this.$message.info('没有查问到属性！')
      }
      _this.loading = false
    },
    error: function () {_this.$message.info('没有查问到属性！')
      _this.loading = false
    },
  })
}

// 这么调用
this.doSqlQuery('SmID=' + this.relationListCode[1], layer.DataService, layer.SurMapDataSet, layer.DataSource)

设置图层透明度

function translucentLayers(scene, alpha) {for (var i = 0; i < scene.layers.layerQueue.length; i++) {var layer = scene.layers.findByIndex(i);
    if (layer) {layer.style3D.fillForeColor.alpha = parseFloat(alpha);
    }
  }
}

设置影像透明度

const _layers = viewer.imageryLayers._layers
for (let i = 0, len = _layers.length; i < len; i++) {_layers[i].alpha = 0.6
}

监听点击事件

const events = {
    click: "LEFT_CLICK",
    wheel: "WHEEL",
    middleClick: "MIDDLE_DOWN",
    mouseMove: "MOUSE_MOVE"
}
viewer.screenSpaceEventHandler.setInputAction(e => {this.$emit(key, e)
}, Cesium.ScreenSpaceEventType[events[key]])

通过超图名称获取图层

viewer.scene.layers.find(SuperLayerName)

设置更改构件色彩

layer.setObjsColor(ids, cesiumColor);

其中:

• layer是图层对象
• ids是 smid 数组
• cesiumColor是 cesium 的色彩对象

如果只须要影响一个构件应用此办法

layer.setOnlyObjsColor(smId, cesiumColor);

通过图层获取其下的所有 smid

layer._selections

返回的是 [“3762”, “123”] 这样的 smid 汇合

暗藏构件

layer.setObjsVisible(ids, bool)

其中

• layer是图层对象
• ids是 smid 汇合
• bool是是否显示, true为显示 false为暗藏

将图层下的构件全副显示只须要将 ids 设置为 [] 即可

layer.setObjsVisible([], false);

如果只须要影响一个构件应用此办法

layer.setOnlyObjsVisible(smid, bool)

设置光源追随摄像头

// 设置光源追随
var degZ = 0;// 程度夹角
var degX = 0; // 垂直夹角
scene.sun.show = false;
// 设置环境光的强度
scene.lightSource.ambientLightColor = new Cesium.Color(0.86,0.86, 0.86, 1);

// var position1 = new Cesium.Cartesian3.fromDegrees(117.61862360516848 - 0.000009405717451407729 * 86.6, 40.2317259501307 - 0.00000914352698135 * 50, 350);
// 设置初始光源地位
var position1 = new Cesium.Cartesian3.fromDegrees(117.61862360516848, 32.19180102105889, 350);
var targetPosition1 = new Cesium.Cartesian3.fromDegrees(117.61862360516848, 32.19180102105889, 130);
var dirLightOptions = {
  targetPosition: targetPosition1,
  color: new Cesium.Color(1.0, 1.0, 1.0, 1),
  intensity: 0.7
};
directionalLight_1  = new Cesium.DirectionalLight(position1, dirLightOptions);
scene.addLightSource(directionalLight_1);
scene.postRender.addEventListener(function () { // 每一帧 十分耗性能
  var cameraPosition = Cesium.Cartesian3.clone(scene.camera.position);
  var length = 100;
  var quad1 = Cesium.Quaternion.fromAxisAngle(viewer.scene.camera.upWC, Cesium.Math.toRadians(degZ));
  var quad2 = Cesium.Quaternion.fromAxisAngle(viewer.scene.camera.rightWC, Cesium.Math.toRadians(degX));
  var resQuad = Cesium.Quaternion.add(quad2, quad1, quad1);
  var rotation = Cesium.Matrix3.fromQuaternion(resQuad);
  var direction = Cesium.Matrix3.multiplyByVector(rotation, viewer.scene.camera.directionWC, new Cesium.Cartesian3());
  var targetPosition2 = Cesium.Cartesian3.add(
      viewer.scene.camera.positionWC,
      Cesium.Cartesian3.multiplyByScalar(direction, length, new Cesium.Cartesian3()),
      new Cesium.Cartesian3());
  directionalLight_1.position = cameraPosition;
  directionalLight_1.targetPosition = targetPosition2;
});

点击某个点呈现弹窗并且应用 Vue 组件实现

Pop.js

// 创立弹窗对象的办法
import Vue from 'vue'

const Popup = function (info, component) {this.constructor(info, component)

Popup.prototype.id = 0
Popup.prototype.constructor = function (info, component) {

export default Popup

应用时

new Popup({
  viewer,
  geometry: e.data.position,
  title: '门禁信息',
  data: '<div>Fuck</div>'
}, AccessControl)

其中: AccessControl是 vue 组件!

import AccessControl from '@/components/AccessControl.vue'

次要应用了 Vue 的 $mount() 办法

获取相机信息

viewer.scene.camera

将世界坐标转换为屏幕坐标

Cesium.SceneTransforms.wgs84ToWindowCoordinates(scene, geometry)

其中

• scene 是场景
• geometry 是世界坐标

依据 CSS 色彩值创立一个 Color 实例。

Cesium.Color.fromCssColorString('#67ADDF');

Cesium 色彩数值和惯例 HTML 色彩数值的转换公式

通过一番调研，发现 Cesium.Color(r, g,b,a)中, r,g,b,a 的值均在 0 - 1 之间. 和 html rgba 的换算如下:

Cesium.Color(html.r/255, html.g/255, html.b/255, html.a)

js 办法如下, 其中 colorString 必须是 16 进制色

colorConvert(colorString) {
  const red =
    parseInt(colorString.slice(1, 3), 16) / 255;
  const green =
    parseInt(colorString.slice(3, 5), 16) / 255;
  const blue =
    parseInt(colorString.slice(5, 7), 16) / 255;
  return new Cesium.Color(red, green, blue, 1);
},

聚合 label、广告牌

_this.clusteringlayer = new Cesium.CustomDataSource('clusteringlayer');

const pixelRange = 50;
const minimumClusterSize = 2;
const enabled = true;
// 启用集群
_this.clusteringlayer.clustering.enabled = enabled;
// 设置扩大屏幕空间边界框的像素范畴。_this.clusteringlayer.clustering.pixelRange = pixelRange;
// 能够群集的最小屏幕空间对象
_this.clusteringlayer.clustering.minimumClusterSize = minimumClusterSize;
// 将进行实体的广告牌聚类
_this.clusteringlayer.clustering.clusterBillboards = true;

var removeListener;
// 自定义地图图钉生成为画布元素
var pinBuilder = new Cesium.PinBuilder();
customStyle();

function customStyle() {if (Cesium.defined(removeListener)) {removeListener();
  removeListener = undefined;
} else {removeListener = _this.clusteringlayer.clustering.clusterEvent.addEventListener(function(clusteredEntities, cluster) {
    cluster.label.show = false;
    cluster.billboard.show = true;
    cluster.billboard.id = cluster.label.id;
    cluster.billboard.verticalOrigin = Cesium.VerticalOrigin.BOTTOM;
    cluster.billboard.disableDepthTestDistance = Number.POSITIVE_INFINITY;
    // 文本将被调整为尽可能大的大小同时仍齐全蕴含在图钉中
    // var pinimg = pinBuilder.fromText(clusteredEntities.length, Cesium.Color.BLUE, 50).toDataURL();
    // var pinimg='./images/location4.png';
    if (clusteredEntities?.[0]?._name) cluster.billboard.image = _this.renderText(clusteredEntities[0]._name, undefined, undefined, 14);
    //cluster.billboard.scale=0.2;
  });
}
}

// 对于须要聚合的实体应用
// _this.clusteringlayer.entities.add(entity)

// 增加到 viewer 中
viewer.dataSources.add(_this.clusteringlayer)

超图动静绘标汇总

初始化绘标以及加载标注库

methods: {
    // 初始化
    InitPlot(viewer, serverUrl) {if (!viewer) {return;}
      const _this = this;
      const plottingLayer = new Cesium.PlottingLayer(
        viewer.scene,
        'plottingLayer'
      );
    
      this.plottingLayer = plottingLayer;
      viewer.scene.plotLayers.add(plottingLayer);
    
      const plotting = Cesium.Plotting.getInstance(
        serverUrl,
        viewer.scene
      );
    
      this.plotting = plotting;
    
      this.plotEditControl = new Cesium.PlotEditControl(
        viewer.scene,
        plottingLayer
      ); // 编辑控件
      this.plotEditControl.activate();
      this.plotDrawControl = new Cesium.PlotDrawControl(
        viewer.scene,
        plottingLayer
      ); // 绘制控件
      this.plotDrawControl.drawControlEndEvent.addEventListener(function() {
          // 标绘完结，激活编辑控件
          _this.plotEditControl.activate();}
      );
    
      this.loadSymbolLib(plotting);
    
      console.log(plotting.getDefaultStyle());
    
      // 一些缺省属性，不须要能够删除
      plotting.getDefaultStyle().lineWidth = this.thickness;
      plotting.getDefaultStyle().lineColor = this.colorConvert(this.color);
      plotting.getDefaultStyle().defaultFlag = true;},
    // 加载标注库
    loadSymbolLib(plotting) {const symbolLibManager = plotting.getSymbolLibManager();
      if (symbolLibManager.isInitializeOK()) {// isok} else {
        symbolLibManager.initializecompleted.addEventListener(function(result) {if (result.libIDs.length !== 0) {// isok}
          }
        );
        symbolLibManager.initializeAsync();}
    },
}

只须要执行 InitPlot 办法即可

this.InitPlot(
  viewer,
  '/iserver/services/plot-jingyong/rest/plot'
);

不应用面板如何画标

handleDraw(id, code) {this.plotDrawControl.setAction(id, code);
  this.plotDrawControl.activate();
  this.plotEditControl.deactivate();},

绘标须要一个 id 和code, 那么如何获取 id 和 code？

• 如果是根本标记(线之类的)

  http://support.supermap.com.c…能够点击画好的标注查看属性，属性中有 id 和 code

• 除了根本标记外

  http://${ip 或域名}/iserver/services/plot-jingyong/rest/plot/symbolLibs/能够看到所有的标记库

如何预约义款式

批改超图默认的标注色彩等

 plotting.getDefaultStyle().lineWidth = this.thickness;

能够从控制台中看到 plotting.getDefaultStyle() 中所有的缺省属性，间接赋值就能够批改缺省属性
