Class: PolylineVolumeOutlineGeometry

PolylineVolumeOutlineGeometry

new PolylineVolumeOutlineGeometry(options)

A description of a polyline with a volume (a 2D shape extruded along a polyline).
Parameters:
Name Type Description
options Object Object with the following properties:
Properties
Name Type Attributes 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 <optional>
 Ellipsoid.WGS84 The ellipsoid to be used as a reference.
granularity Number <optional>
 CesiumMath.RADIANS_PER_DEGREE The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
cornerType CornerType <optional>
 CornerType.ROUNDED Determines the style of the corners.

  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;

Methods

(static) createGeometry(polylineVolumeOutlineGeometry) → {Geometry|undefined}

Computes the geometric representation of the outline of a polyline with a volume, including its vertices, indices, and a bounding sphere.
Parameters:
Name Type Description
polylineVolumeOutlineGeometry PolylineVolumeOutlineGeometry A description of the polyline volume outline.
Source:
Returns:
The computed vertices and indices.
Type
Geometry | undefined

(static) pack(value, array, startingIndexopt) → {Array.<Number>}

Stores the provided instance into the provided array.
Parameters:
Name Type Attributes Default Description
value PolylineVolumeOutlineGeometry The value to pack.
array Array.<Number> The array to pack into.
startingIndex Number <optional>
 0 The index into the array at which to start packing the elements.
Source:
Returns:
The array that was packed into
Type
Array.<Number>

(static) unpack(array, startingIndexopt, resultopt) → {PolylineVolumeOutlineGeometry}

Retrieves an instance from a packed array.
Parameters:
Name Type Attributes Default Description
array Array.<Number> The packed array.
startingIndex Number <optional>
 0 The starting index of the element to be unpacked.
result PolylineVolumeOutlineGeometry <optional>
 The object into which to store the result.
