PolylineVolumeGeometry

new PolylineVolumeGeometry

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

Parameters:

Name	Type	Argument	Default	Description
`options.polylinePositions`	Array			An array of Cartesain3 positions that define the center of the polyline volume.
`options.shapePositions`	Number			An array of Cartesian2 positions that define the shape to be extruded along the polyline
`options.ellipsoid`	Ellipsoid	<optional>	Ellipsoid.WGS84	The ellipsoid to be used as a reference.
`options.granularity`	Number	<optional>	CesiumMath.RADIANS_PER_DEGREE	The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
`options.height`	Number	<optional>	0	The distance between the ellipsoid surface and the positions.
`options.vertexFormat`	VertexFormat	<optional>	VertexFormat.DEFAULT	The vertex attributes to be computed.
`options.cornerType`	Boolean	<optional>	CornerType.ROUNDED	Determines the style of the corners.

Throws:

DeveloperError : options.polylinePositions is required.
DeveloperError : options.shapePositions is required.

Example

var volume = new PolylineVolumeGeometry({
    vertexFormat : VertexFormat.POSITION_ONLY,
    polylinePositions : ellipsoid.cartographicArrayToCartesianArray([
        Cartographic.fromDegrees(-72.0, 40.0),
        Cartographic.fromDegrees(-70.0, 35.0)
    ]),
    shapePositions : Shapes.compute2DCircle(100000.0)
});
