目标将西南石油大学部分区域围起来，然后引个标签显示名称，最后弄个飞机绕学校飞（这个时间有点晚了，明天弄)
围墙:
wall:{positions:Cesium.Cartesian3.fromDegreesArrayHeights([104.173,30.822,500,104.178,30.837,500,104.19,30.837, 500,104.185,30.82,500,104.173,30.822,500,]),material:Cesium.Color.RED.withAlpha(.4),outline: true,},线条
polyline:{positions:Cesium.Cartesian3.fromDegreesArrayHeights([104.18,30.83,0,104.18,30.83,1600]),material:Cesium.Color.BLUE,width:5},标签，这个坐标你需要在外面设定
new Cesium.Entity({position:Cesium.Cartesian3.fromDegrees(104.18,30.83,1650),label: {text: "好的大学没有围墙！！", font: "14px sans-serif", showBackground: true,backgroundColor:new Cesium.Color(50,50,50,.6)},})然后就是加载一个飞机，文档里面说了只能gltf格式
飞机的位置也要在写在外面，会和标签重合，所以重新创建一个对象,
模型需要自己下载
var plane=new Cesium.Entity({position:Cesium.Cartesian3.fromDegrees(104.173,30.822,600),model: {uri:"src/assets/gltf/plane/scene.gltf",minimumPixelSize: 128, //模型最小像素maximumScale: 200, //模型最大放大倍数},orientation:Cesium.Transforms.headingPitchRollQuaternion(Cesium.Cartesian3.fromDegrees(104.173,30.822,600),new Cesium.HeadingPitchRoll(Cesium.Math.toRadians(-90), // 设置顺时针旋转的角度值Cesium.Math.toRadians(0),Cesium.Math.toRadians(0)))})效果
