# SimplePolylineGeometry

#### new SimplePolylineGeometry(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.
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.
##### 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);``````

### Members

#### packedLength :Number

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

### Methods

#### staticSimplePolylineGeometry.createGeometry(simplePolylineGeometry) → Geometry

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.

#### staticSimplePolylineGeometry.pack(value, array, startingIndex)

Stores the provided instance into the provided array.
Name Type Default Description
`value` Object 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.

#### staticSimplePolylineGeometry.unpack(array, startingIndex, result)

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.
