new PolylineVolumeOutlineGeometry(options)

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 Number 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.
