PolylineGeometry

new PolylineGeometry(options)

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. The polyline is capable of displaying with a material.
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.
width Number 1.0 optional The width in pixels.
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.PolylineGeometry({
  positions : Cesium.Cartesian3.fromDegreesArray([
    0.0, 0.0,
    5.0, 0.0,
    5.0, 5.0
  ]),
  width : 10.0
});
var geometry = Cesium.PolylineGeometry.createGeometry(polyline);
