PolylineGraphics

new Cesium.PolylineGraphics(options)
DataSources/PolylineGraphics.js 40

Describes a polyline. The first two positions define a line segment, and each additional position defines a line segment from the previous position. The segments can be linear connected points, great arcs, or clamped to terrain.

Members

arcType : Property|undefined
DataSources/PolylineGraphics.js 142

Gets or sets the ArcType Property specifying whether the line segments should be great arcs, rhumb lines or linearly connected.
Default Value: ArcType.GEODESIC

clampToGround : Property|undefined
DataSources/PolylineGraphics.js 151

Gets or sets the boolean Property specifying whether the polyline should be clamped to the ground.
Default Value: false

classificationType : Property|undefined
DataSources/PolylineGraphics.js 177

Gets or sets the ClassificationType Property specifying whether this polyline will classify terrain, 3D Tiles, or both when on the ground.
Default Value: ClassificationType.BOTH

readonly definitionChanged : Event
DataSources/PolylineGraphics.js 78

Gets the event that is raised whenever a property or sub-property is changed or modified.

depthFailMaterial : MaterialProperty
DataSources/PolylineGraphics.js 134

Gets or sets the Property specifying the material used to draw the polyline when it fails the depth test.

Requires the EXT_frag_depth WebGL extension to render properly. If the extension is not supported, there may be artifacts.

Default Value: undefined

distanceDisplayCondition : Property|undefined
DataSources/PolylineGraphics.js 167

Gets or sets the DistanceDisplayCondition Property specifying at what distance from the camera that this polyline will be displayed.

granularity : Property|undefined
DataSources/PolylineGraphics.js 114

Gets or sets the numeric Property specifying the angular distance between each latitude and longitude if arcType is not ArcType.NONE and clampToGround is false.
Default Value: Cesium.Math.RADIANS_PER_DEGREE

material : MaterialProperty
DataSources/PolylineGraphics.js 122

Gets or sets the Property specifying the material used to draw the polyline.
Default Value: Color.WHITE

positions : Property|undefined
DataSources/PolylineGraphics.js 98

Gets or sets the Property specifying the array of Cartesian3 positions that define the line strip.

shadows : Property|undefined
DataSources/PolylineGraphics.js 160

Get or sets the enum Property specifying whether the polyline casts or receives shadows from light sources.
Default Value: ShadowMode.DISABLED

show : Property|undefined
DataSources/PolylineGraphics.js 90

Gets or sets the boolean Property specifying the visibility of the polyline.
Default Value: true

width : Property|undefined
DataSources/PolylineGraphics.js 106

Gets or sets the numeric Property specifying the width in pixels.
Default Value: 1.0

zIndex : ConstantProperty|undefined
DataSources/PolylineGraphics.js 185

Gets or sets the zIndex Property specifying the ordering of the polyline. Only has an effect if `clampToGround` is true and polylines on terrain is supported.
Default Value: 0
