PolygonGraphics

new Cesium.PolygonGraphics(options)

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.

成员(属性)

Gets or sets the ArcType Property specifying the type of lines the polygon edges use.
默认值: ArcType.GEODESIC
Gets or sets the ClassificationType Property specifying whether this polygon will classify terrain, 3D Tiles, or both when on the ground.
默认值: ClassificationType.BOTH
Gets or sets a boolean specifying whether or not the bottom of an extruded polygon is included.
Gets or sets a boolean specifying whether or not the top of an extruded polygon is included.
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.
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.
默认值: HeightReference.NONE
Gets or sets the boolean Property specifying whether the polygon is filled with the provided material.
默认值: true
Gets or sets the numeric Property specifying the angular distance between points on the polygon.
默认值: {CesiumMath.RADIANS_PER_DEGREE}
Gets or sets the numeric Property specifying the constant altitude of the polygon.
默认值: 0.0
Gets or sets the Property specifying the HeightReference.
默认值: HeightReference.NONE
Gets or sets the Property specifying the PolygonHierarchy.
Gets or sets the Property specifying the material used to fill the polygon.
默认值: Color.WHITE
Gets or sets the Property specifying whether the polygon is outlined.
默认值: false
Gets or sets the Property specifying the Color of the outline.
默认值: Color.BLACK
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}.

默认值: 1.0
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.
Get or sets the enum Property specifying whether the polygon casts or receives shadows from light sources.
默认值: ShadowMode.DISABLED
Gets or sets the boolean Property specifying the visibility of the polygon.
默认值: true
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.
默认值: 0
A Property specifying texture coordinates as a PolygonHierarchy of Cartesian2 points. Has no effect for ground primitives.
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.
默认值: 0
