# PolylineVolumeOutlineGeometry

#### new Cesium.PolylineVolumeOutlineGeometry(options)
Core/PolylineVolumeOutlineGeometry.js 133

  A description of a polyline with a volume (a 2D shape extruded along a polyline).

  Name | Type | Description
  --- | --- | ---
  `options` | Object | Object with the following properties:
  Name | Type | Default | Description
  --- | --- | --- | ---
  `polylinePositions` | Array.<Cartesian3> |  | An array of positions that define the center of the polyline volume.
  `shapePositions` | Array.<Cartesian2> |  | An array of positions that define the shape to be extruded along the polyline
  `ellipsoid` | Ellipsoid | `Ellipsoid.WGS84` | optional The ellipsoid to be used as a reference.
  `granularity` | Number | `CesiumMath.RADIANS_PER_DEGREE` | optional The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
  `cornerType` | CornerType | `CornerType.ROUNDED` | optional Determines the style of the corners.

  ##### Example:

      function computeCircle(radius) {
        var positions = [];
        for (var i = 0; i < 360; i++) {
          var radians = Cesium.Math.toRadians(i);
          positions.push(new Cesium.Cartesian2(radius * Math.cos(radians), radius * Math.sin(radians)));
        }
        return positions;
      }

      var volumeOutline = new Cesium.PolylineVolumeOutlineGeometry({
        polylinePositions : Cesium.Cartesian3.fromDegreesArray([
          -72.0, 40.0,
          -70.0, 35.0
        ]),
        shapePositions : computeCircle(100000.0)
      });

### Members

#### packedLength : Number
Core/PolylineVolumeOutlineGeometry.js 161

  The number of elements used to pack the object into an array.

### Methods

#### staticCesium.PolylineVolumeOutlineGeometry.createGeometry(polylineVolumeOutlineGeometry) → Geometry|undefined
Core/PolylineVolumeOutlineGeometry.js 282

  Computes the geometric representation of the outline of a polyline with a volume, including its vertices, indices, and a bounding sphere.

  Name | Type | Description
  --- | --- | ---
  `polylineVolumeOutlineGeometry` | PolylineVolumeOutlineGeometry | A description of the polyline volume outline.

  ##### Returns:

  The computed vertices and indices.

#### staticCesium.PolylineVolumeOutlineGeometry.pack(value, array, startingIndex)
Core/PolylineVolumeOutlineGeometry.js 171

  Stores the provided instance into the provided array.

  Name | Type | Default | Description
  --- | --- | --- | ---
  `value` | PolylineVolumeOutlineGeometry |  | The value to pack.
  `array` | Array.<Number> |  | The array to pack into.
  `startingIndex` | Number | `0` | optional The index into the array at which to start packing the elements.

#### staticCesium.PolylineVolumeOutlineGeometry.unpack(array, startingIndex, result) → PolylineVolumeOutlineGeometry
Core/PolylineVolumeOutlineGeometry.js 226

  Retrieves an instance from a packed array.

  Name | Type | Default | Description
  --- | --- | --- | ---
  `array` | Array.<Number> |  | The packed array.
  `startingIndex` | Number | `0` | optional The starting index of the element to be unpacked.
  `result` | PolylineVolumeOutlineGeometry |  | optional The object into which to store the result.

  ##### Returns:

  The modified result parameter or a new PolylineVolumeOutlineGeometry instance if one was not provided.
