我是用这个方法创建的圆柱体
let ellipseEntity = entities.add({
                position : center,
               orientation:Cesium.Transforms.headingPitchRollQuaternion(center, new Cesium.HeadingPitchRoll(h+1.5707963267948966,-(p+1.5707963267948966),0)),
                 cylinder : {
                    length:d,
                    topRadius:that.zj,
                    bottomRadius:that.zj,
                    material : color,
                    fill : true,
                    outline : false,
                    outlineColor : Cesium.Color.BLACK,
                    outlineWidth : 1
                }
            });
