知道自己鼠标在某个竖直平面上的经纬度信息在这个竖直的平面上的实时坐标

鼠标放上去就开启map.on(mars3d.EventType.mouseMove，结合以下方法实现

      callback: function (e) {
        // 经纬度
        const mpt = LngLatPoint.fromCartesian(e.cartesian)

        const ptNew = proj4Trans([mpt.lng, mpt.lat], "EPSG:4326", CRS.CGCS2000_GK_Zone_3)

        const inhtml = `
         ${map.getLangText("_经度")}:${mpt.lng}, ${map.getLangText("_纬度")}:${mpt.lat}, ${map.getLangText("_海拔")}:${mpt.alt},
         ${map.getLangText("_横坐标")}:${ptNew[0].toFixed(1)}, ${map.getLangText("_纵坐标")}:${ptNew[1].toFixed(1)} (CGCS2000)
        `
        globalAlert(inhtml, map.getLangText("_位置信息"))

        // 打印方便测试
        const ptX = formatNum(e.cartesian.x, 1) // 笛卡尔
        const ptY = formatNum(e.cartesian.y, 1)
        const ptZ = formatNum(e.cartesian.z, 1)
        logInfo(`经纬度：${mpt.toString()} , 笛卡尔：${ptX},${ptY},${ptZ}`)
      }
