实现代码：

复制代码

export function onMounted(mapInstance) {
  map = mapInstance // 记录首次创建的map

  // 添加参考三维模型
  const tiles3dLayer = new mars3d.layer.TilesetLayer({
    name: "合肥国家大学科技园",
    url: "//data.mars3d.cn/3dtiles/qx-hfdxy/tileset.json",
    position: { alt: 80 },
    maximumScreenSpaceError: 1
  })
  map.addLayer(tiles3dLayer)

  const graphicLayer = new mars3d.layer.ArcGisWfsLayer({
    name: "兴趣点",
    url: "//server.mars3d.cn/arcgis/rest/services/mars/hefei/MapServer/1",
    where: " NAME like '%大学%' ",
    minimumLevel: 15,
    symbol: {
      type: "billboardP",
      styleOptions: {
        image: "img/marker/mark-blue.png",
        verticalOrigin: Cesium.VerticalOrigin.BOTTOM,
        label: {
          text: "{NAME}",
          font_size: 15,
          color: "#ffffff",
          outline: true,
          outlineColor: "#000000",
          pixelOffsetY: -30
        }
      }
    },
      clustering: {
      enabled: true,
      pixelRange: 20,
    },
    popup: "名称：{NAME}<br />地址：{address}",
    show: true
  })
  graphicLayer.on(mars3d.EventType.addGraphic, function (event) {
    updateAutoSurfaceHeight(event.graphic)
  })

  map.on(mars3d.EventType.load, function (event) {
    map.addLayer(graphicLayer)
  })
}
