PolylineGeometry

PolylineGeometry

new

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.

Parameters:
Name Type Argument Default Description
options.positions Array An array of Cartesian3 defining the positions in the polyline as a line strip.
options.width Number <optional>
1.0 The width in pixels.
options.colors Array <optional>
undefined An Array of Color defining the per vertex or per segment colors.
options.colorsPerVertex Boolean <optional>
false A boolean that determines whether the colors will be flat across each segment of the line or interpolated across the vertices.
Throws:
Example
// A polyline with two connected line segments
var polyline = new PolylineGeometry({
  positions : ellipsoid.cartographicArrayToCartesianArray([
    Cartographic.fromDegrees(0.0, 0.0),
    Cartographic.fromDegrees(5.0, 0.0),
    Cartographic.fromDegrees(5.0, 5.0)
  ]),
  width : 10.0
});
var geometry = PolylineGeometry.createGeometry(polyline);
