supermap iclient3d for cesium中entity使用

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)
                )
            )
        })
