PolylineGraphics

new Cesium.PolylineGraphics(options)
DataSources/PolylineGraphics.js 41

Describes a polyline defined as a line strip. 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 or great arcs.
Name Type Description
options Object optional Object with the following properties:
Name Type Default Description
positions Property optional A Property specifying the array of Cartesian3 positions that define the line strip.
followSurface Property true optional A boolean Property specifying whether the line segments should be great arcs or linearly connected.
width Property 1.0 optional A numeric Property specifying the width in pixels.
show Property true optional A boolean Property specifying the visibility of the polyline.
material MaterialProperty Color.WHITE optional A Property specifying the material used to draw the polyline.
depthFailMaterial MaterialProperty optional A property specifiying the material used to draw the polyline when it is below the terrain.
granularity Property Cesium.Math.RADIANS_PER_DEGREE optional A numeric Property specifying the angular distance between each latitude and longitude if followSurface is true.
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.

Members

readonlydefinitionChanged : Event
DataSources/PolylineGraphics.js 74

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

depthFailMaterial : MaterialProperty
DataSources/PolylineGraphics.js 106

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
