A description of a polyline with a volume (a 2D shape extruded along a polyline).
alias PolylineVolumeGeometry
- The options object takes the following properties
- {Cartesian3[]} options.polylinePositions An array of Cartesian3 positions that define the center of the polyline volume.
- {Cartesian2[]} options.shapePositions An array of Cartesian2 positions that define the shape to be extruded along the polyline
- {Ellipsoid} [options.ellipsoid=Ellipsoid.WGS84] The ellipsoid to be used as a reference.
- {Number} [options.granularity=CesiumMath.RADIANS_PER_DEGREE] The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
- {VertexFormat} [options.vertexFormat=VertexFormat.DEFAULT] The vertex attributes to be computed.
- {CornerType} [options.cornerType=CornerType.ROUNDED] Determines the style of the corners.
