GroundPolylineGeometry

new LSGlobe.GroundPolylineGeometry(options)
Core/GroundPolylineGeometry.js 74

A description of a polyline on terrain or 3D Tiles. Only to be used with GroundPolylinePrimitive.
Name Type Description
options Object Options with the following properties:
Name Type Default Description
positions Array.<Cartesian3> An array of Cartesian3 defining the polyline's points. Heights above the ellipsoid will be ignored.
width Number 1.0 optional The screen space width in pixels.
granularity Number 9999.0 optional The distance interval in meters used for interpolating options.points. Defaults to 9999.0 meters. Zero indicates no interpolation.
loop Boolean false optional Whether during geometry creation a line segment will be added between the last and first line positions to make this Polyline a loop.
arcType ArcType ArcType.GEODESIC optional The type of line the polyline segments must follow. Valid options are ArcType.GEODESIC and ArcType.RHUMB.
Throws:
Example:
var positions = LSGlobe.Cartesian3.fromDegreesArray([
  -112.1340164450331, 36.05494287836128,
  -112.08821010582645, 36.097804071380715,
  -112.13296079730024, 36.168769146801104

Members

arcType : ArcType
Core/GroundPolylineGeometry.js 122

The type of path the polyline must follow. Valid options are ArcType.GEODESIC and ArcType.RHUMB.
Default Value: ArcType.GEODESIC

granularity : Boolean
Core/GroundPolylineGeometry.js 107

The distance interval used for interpolating options.points. Zero indicates no interpolation. Default of 9999.0 allows centimeter accuracy with 32 bit floating point.
Default Value: 9999.0

loop : Boolean
Core/GroundPolylineGeometry.js 115

Whether during geometry creation a line segment will be added between the last and first line positions to make this Polyline a loop. If the geometry has two positions this parameter will be ignored.
Default Value: false

width : Number
Core/GroundPolylineGeometry.js 97

The screen space width in pixels.

Methods

The array that was packed into

static LSGlobe.GroundPolylineGeometry.unpack(array, startingIndex, result)
Core/GroundPolylineGeometry.js 332

Retrieves an instance from a packed array.
Name Type Default Description
array Array.<Number> The packed array.
startingIndex Number 0 optional The starting index of the element to be unpacked.
result PolygonGeometry optional The object into which to store the result.
