WEBGL中如何使用entity建立圆形的wall？

Answer 1

圆形的wall与正常的wall制作方法类似，把postitions的范围改成圆就可以。

positions : Cesium.Cartesian3.fromDegreesArray(
            [-115.0, 50.0,
             -112.5, 50.0,
             -110.0, 50.0,
             -107.5, 50.0,
             -105.0, 50.0,
             -102.5, 50.0,
             -100.0, 50.0,
             -97.5, 50.0,
             -95.0, 50.0,
             -92.5, 50.0,
             -90.0, 50.0]),
        maximumHeights : [ //上高
            100000, 200000, 100000, 200000, 100000, 200000, 
            100000, 200000, 100000, 200000, 100000],
        minimumHeights : [  //下高
            0, 100000,  0, 100000, 0, 100000, 0, 100000, 0,
            100000, 0],
