Segment display is not connected

I use the following method to draw polyline volume,but find the segment display is not connected,Why?

//Add Road Path
  function computeCircle(radius) {
    var positions = ;
    for (var i = 0; i < 360; i++) {
      var radians = BeyonMap.Math.toRadians(i);
      positions.push(new BeyonMap.Cartesian2(radius * Math.cos(radians), radius * Math.sin(radians)));
    }
    return positions;
  }

  var promiseRoad =BeyonMap.GeoJsonDataSource.load('./Test.geojson');
  promiseRoad.then(function(dataSource) {
    var entities = dataSource.entities.values;
    var nowtime = BeyonMap.JulianDate.now();
    for (var i = 0; i < entities.length; i++) {
      var entity = entities[i];
      var redLine = viewer.entities.add({
        polylineVolume : {
          positions : entity.polyline.positions.getValue(nowtime),
          shape : computeCircle(5.0),
          outline : false,
          material : BeyonMap.Color.WHITE
        }
      });
    }
  }).otherwise(function(error){
    //Display any errrors encountered while loading.
    window.alert(error);
  });

Hello,

I believe this is a bug in Cesium. We’re not rendering PolylineVolumes that have a short length.

I’ve submitted a fix here: https://github.com/AnalyticalGraphicsInc/cesium/pull/3305

Best,
