<p class="description">
A renderable collection of polylines.
<br /><br />
<div align="center">
<img src="images/Polyline.png" width="400" height="300" /><br />
Example polylines
</div>
<br /><br />
Polylines are added and removed from the collection using <a href="PolylineCollection.html#add">PolylineCollection#add</a>
and <a href="PolylineCollection.html#remove">PolylineCollection#remove</a>.
</p>
<h5>Performance:</h5>
<p class="description">For best performance, prefer a few collections, each with many polylines, to
many collections with only a few polylines each. Organize collections so that polylines
with the same update frequency are in the same collection, i.e., polylines that do not
change should be in one collection; polylines that change every frame should be in another
collection; and so on.</p>
<h5>Example</h5>
<pre class="code brush: js">// Create a polyline collection with two polylines
var polylines = new PolylineCollection(undefined);
polylines.add({positions:ellipsoid.cartographicDegreesToCartesians([
new Cartographic2(-75.10, 39.57),
new Cartographic2(-77.02, 38.53),
new Cartographic2(-80.50, 35.14),
new Cartographic2(-80.12, 25.46)]),
width:2
});
polylines.add({positions:ellipsoid.cartographicDegreesToCartesians([
new Cartographic2(-73.10, 37.57),
new Cartographic2(-75.02, 36.53),
new Cartographic2(-78.50, 33.14),
new Cartographic2(-78.12, 23.46)]),
width:4
});</pre>

<div class="description">
The 4x4 transformation matrix that transforms each polyline in this collection from model to world coordinates.
When this is the identity matrix, the polylines are drawn in world coordinates, i.e., Earth's WGS84 coordinates.
Local reference frames can be used by providing a different transformation matrix, like that returned
by <a href="Transforms.html#eastNorthUpToFixedFrame">Transforms.eastNorthUpToFixedFrame</a>. This matrix is available to GLSL vertex and fragment
shaders via <a href="czm_model.html">czm_model</a> and derived uniforms.

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic

Once an object is destroyed, it should not be used; calling any function other than

assign the return value (<code>undefined</code>) to the object as done in the example.

Returns the polyline in the collection at the specified index. Indices are zero-based
