Polygon
This page describes the possible content of a CZML document or stream. Please read CZML Structure for an explanation of how a CZML document is put together.
A polygon, which is a closed figure on the surface of the Earth.
Interpolatable: no
show - Boolean
Whether or not the polygon is shown.
Default: true
positions - PositionList - Required
The array of positions defining a simple polygon.
holes - PositionListOfLists
The array of arrays of positions defining holes in the polygon.
arcType - ArcType
The type of arc that should connect the positions of the polygon.
Default: GEODESIC
height - Double
The height of the polygon when perPositionHeight is false.
Default: 0.0
heightReference - HeightReference
The height reference of the polygon, which indicates if height is relative to terrain or not.
Default: NONE
extrudedHeight - Double
The extruded height of the polygon.
extrudedHeightReference - HeightReference
The extruded height reference of the polygon, which indicates if extrudedHeight is relative to terrain or not.
Default: NONE
stRotation - Double
The rotation of any applied texture. A positive rotation is counter-clockwise.
Default: 0.0
granularity - Double
The sampling distance, in radians.
Default: π / 180.0
fill - Boolean
Whether or not the polygon is filled.
Default: true
material - Material
The material to use to fill the polygon.
Default: solid white
outline - Boolean
Whether or not the polygon is outlined.
Default: false
outlineColor - Color
The color of the polygon outline.
Default: black
outlineWidth - Double
The width of the polygon outline.
Default: 1.0
perPositionHeight - Boolean
Whether to use the height of each position to define the polygon or to use height as a constant height above the surface.
Default: false
closeTop - Boolean
Whether to close the top of the polygon.
Default: true
closeBottom - Boolean
Whether to close the bottom of the polygon.
Default: true
shadows - ShadowMode
Whether or not the polygon casts or receives shadows.
Default: DISABLED
distanceDisplayCondition - DistanceDisplayCondition
The display condition specifying the distance from the camera at which this polygon will be displayed.
classificationType - ClassificationType
Whether a classification affects terrain, 3D Tiles, or both.
Default: BOTH
zIndex - Integer
The z-index of the polygon, used for ordering ground geometry. Only has an effect if the polygon is constant, and height and extrudedHeight are not specified.
Default: 0
