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)
});

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.
