PolylineGraphics

new Cesium.PolylineGraphics(options)

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.
Name Type Description
options Object optional Object with the following properties:
Name Type Default Description
show Property true optional A boolean Property specifying the visibility of the polyline.
positions Property optional A Property specifying the array of Cartesian3 positions that define the line strip.
width Property 1.0 optional A numeric Property specifying the width in pixels.
granularity Property Cesium.Math.RADIANS_PER_DEGREE optional A numeric Property specifying the angular distance between each latitude and longitude if arcType is not ArcType.NONE.
material MaterialProperty Color.WHITE optional A Property specifying the material used to draw the polyline.
depthFailMaterial MaterialProperty optional A property specifying the material used to draw the polyline when it is below the terrain.
arcType ArcType ArcType.GEODESIC optional The type of line the polyline segments must follow.
clampToGround Property false optional A boolean Property specifying whether the Polyline should be clamped to the ground.
shadows Property ShadowMode.DISABLED optional An enum Property specifying whether the polyline casts or receives shadows from each light source.
distanceDisplayCondition Property optional A Property specifying at what distance from the camera that this polyline will be displayed.
classificationType Property ClassificationType.BOTH optional An enum Property specifying whether this polyline will classify terrain, 3D Tiles, or both when on the ground.
zIndex Property 0 optional A Property specifying the zIndex used for ordering ground geometry. Only has an effect if `clampToGround` is true and polylines on terrain is supported.

Members

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

readonlydefinitionChanged : Event

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

Gets or sets the DistanceDisplayCondition Property specifying at what distance from the camera that this polyline will be displayed.
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
Gets or sets the Property specifying the material used to draw the polyline.
Default Value: Color.WHITE
Gets or sets the Property specifying the array of Cartesian3 positions that define the line strip.
Get or sets the enum Property specifying whether the polyline casts or receives shadows from each light source.
Default Value: ShadowMode.DISABLED
Gets or sets the boolean Property specifying the visibility of the polyline.
Default Value: true
Gets or sets the numeric Property specifying the width in pixels.
Default Value: 1.0
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
