Describes a polygon defined by an hierarchy of linear rings which make up the outer shape and any nested holes.
The polygon conforms to the curvature of the globe and can be placed on the surface or
at altitude and can optionally be extruded into a volume.

Members
arcType : Property|undefined
Gets or sets the
ArcType
Property specifying the type of lines the polygon edges use.
-
Default Value:
ArcType.GEODESIC
classificationType : Property|undefined
Gets or sets the
ClassificationType
Property specifying whether this polygon will classify terrain, 3D Tiles, or both when on the ground.
-
Default Value:
ClassificationType.BOTH
closeBottom : Property|undefined
Gets or sets a boolean specifying whether or not the bottom of an extruded polygon is included.
closeTop : Property|undefined
Gets or sets a boolean specifying whether or not the top of an extruded polygon is included.
readonly definitionChanged : Event
Gets the event that is raised whenever a property or sub-property is changed or modified.
distanceDisplayCondition : Property|undefined
Gets or sets the
DistanceDisplayCondition
Property specifying at what distance from the camera that this polygon will be displayed.
extrudedHeight : Property|undefined
Gets or sets the numeric Property specifying the altitude of the polygon extrusion.
If
PolygonGraphics#perPositionHeight
is false, the volume starts at PolygonGraphics#height
and ends at this altitude.
If PolygonGraphics#perPositionHeight
is true, the volume starts at the height of each PolygonGraphics#hierarchy
position and ends at this altitude.
extrudedHeightReference : Property|undefined
Gets or sets the Property specifying the extruded
HeightReference
.
-
Default Value:
HeightReference.NONE
fill : Property|undefined
Gets or sets the boolean Property specifying whether the polygon is filled with the provided material.
-
Default Value:
true
granularity : Property|undefined
Gets or sets the numeric Property specifying the angular distance between points on the polygon.
-
Default Value:
{CesiumMath.RADIANS_PER_DEGREE}
height : Property|undefined
Gets or sets the numeric Property specifying the constant altitude of the polygon.
-
Default Value:
0.0
heightReference : Property|undefined
Gets or sets the Property specifying the
HeightReference
.
-
Default Value:
HeightReference.NONE
hierarchy : Property|undefined
Gets or sets the Property specifying the
PolygonHierarchy
.
Gets or sets the Property specifying the material used to fill the polygon.
-
Default Value:
Color.WHITE
outline : Property|undefined
Gets or sets the Property specifying whether the polygon is outlined.
-
Default Value:
false
outlineColor : Property|undefined
Gets or sets the Property specifying the
Color
of the outline.
-
Default Value:

outlineWidth : Property|undefined
Gets or sets the numeric Property specifying the width of the outline.
Note: This property will be ignored on all major browsers on Windows platforms. For details, see (@link https://github.com/CesiumGS/cesium/issues/40}.
-
Default Value:
1.0
perPositionHeight : Property|undefined
Gets or sets the boolean specifying whether or not the the height of each position is used.
If true, the shape will have non-uniform altitude defined by the height of each
PolygonGraphics#hierarchy
position.
If false, the shape will have a constant altitude as specified by PolygonGraphics#height
.
shadows : Property|undefined
Get or sets the enum Property specifying whether the polygon
casts or receives shadows from light sources.
-
Default Value:
ShadowMode.DISABLED
show : Property|undefined
Gets or sets the boolean Property specifying the visibility of the polygon.
-
Default Value:
true
stRotation : Property|undefined
Gets or sets the numeric property specifying the rotation of the polygon texture counter-clockwise from north. Only has an effect if textureCoordinates is not defined.
-
Default Value:
0
textureCoordinates : Property|undefined
A Property specifying texture coordinates as a
PolygonHierarchy
of Cartesian2
points. Has no effect for ground primitives.
zIndex : ConstantProperty|undefined
Gets or sets the zIndex Prperty specifying the ordering of ground geometry. Only has an effect if the polygon is constant and neither height or extrudedHeight are specified.
