SimplePolylineGeometry

new Cesium.SimplePolylineGeometry(options)
Core/SimplePolylineGeometry.js 109

A description of a polyline modeled as a line strip; the first two positions define a line segment, and each additional position defines a line segment from the previous position.
Name Type Description
options Object Object with the following properties:
Name Type Default Description
positions Array.<Cartesian3> An array of Cartesian3 defining the positions in the polyline as a line strip.
colors Array.<Color> optional An Array of Color defining the per vertex or per segment colors.
colorsPerVertex Boolean false optional A boolean that determines whether the colors will be flat across each segment of the line or interpolated across the vertices.
followSurface Boolean true optional A boolean that determines whether positions will be adjusted to the surface of the ellipsoid via a great arc.
granularity Number CesiumMath.RADIANS_PER_DEGREE optional The distance, in radians, between each latitude and longitude if options.followSurface=true. Determines the number of positions in the buffer.
ellipsoid Ellipsoid Ellipsoid.WGS84 optional The ellipsoid to be used as a reference.
Throws:
Example:
// A polyline with two connected line segments
var polyline = new Cesium.SimplePolylineGeometry({
  positions : Cesium.Cartesian3.fromDegreesArray([
    0.0, 0.0,
    5.0, 0.0,
    5.0, 5.0
  ])
});
var geometry = Cesium.SimplePolylineGeometry.createGeometry(polyline);

The number of elements used to pack the object into an array.

Methods

staticCesium.SimplePolylineGeometry.createGeometry(simplePolylineGeometry) → Geometry
Core/SimplePolylineGeometry.js 263

Computes the geometric representation of a simple polyline, including its vertices, indices, and a bounding sphere.
Name Type Description
simplePolylineGeometry SimplePolylineGeometry A description of the polyline.
Returns:
The computed vertices and indices.

staticCesium.SimplePolylineGeometry.pack(value, array, startingIndex)
Core/SimplePolylineGeometry.js 149

Stores the provided instance into the provided array.
Name Type Default Description
value SimplePolylineGeometry The value to pack.
array Array.<Number> The array to pack into.
startingIndex Number 0 optional The index into the array at which to start packing the elements.

staticCesium.SimplePolylineGeometry.unpack(array, startingIndex, result) → SimplePolylineGeometry
Core/SimplePolylineGeometry.js 195

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 SimplePolylineGeometry optional The object into which to store the result.
Returns:
The modified result parameter or a new SimplePolylineGeometry instance if one was not provided.
