# 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.
##### 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);``````

### Methods

#### staticPolylineGeometry.createGeometry(polylineGeometry) → Geometry

Computes the geometric representation of a polyline, including its vertices, indices, and a bounding sphere.
Name Type Description
`polylineGeometry` PolylineGeometry A description of the polyline.
