new PolylineGeometry()
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 | Default | Description |
|---|---|---|---|
options.positions |
Cartesian3[] |
An array of Cartesian3 defining the positions in the polyline as a line strip. |
|
options.width |
Number |
1.0
|
optional The width in pixels. |
options.colors |
Color[] |
optional
An Array of Color defining the per vertex or per segment colors. |
|
options.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. |
Throws:
-
DeveloperError : At least two positions are required.
-
DeveloperError : width must be greater than or equal to one.
-
DeveloperError : colors has an invalid length.

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
});
