CoplanarPolygonOutlineGeometry

new LSGlobe.CoplanarPolygonOutlineGeometry(options)
Core/CoplanarPolygonOutlineGeometry.js 73

A description of the outline of a polygon composed of arbitrary coplanar positions.
Name Type Description
options Object Object with the following properties:
Name Type Description
polygonHierarchy PolygonHierarchy A polygon hierarchy that can include holes.
Example:
var polygonOutline = new LSGlobe.CoplanarPolygonOutlineGeometry({
  positions : LSGlobe.Cartesian3.fromDegreesArrayHeights([

     -90.0, 30.0, 1000.0,
     -80.0, 30.0, 1000.0,
     -80.0, 30.0, 0.0
  ])
});
var geometry = LSGlobe.CoplanarPolygonOutlineGeometry.createGeometry(polygonOutline);

Returns:
The computed vertices and indices.

static LSGlobe.CoplanarPolygonOutlineGeometry.fromPositions(options) → CoplanarPolygonOutlineGeometry
Core/CoplanarPolygonOutlineGeometry.js 98

A description of a coplanar polygon outline from an array of positions.
Name Type Description
options Object Object with the following properties:
Name Type Description
positions Array.<Cartesian3> An array of positions that defined the corner points of the polygon.
Returns:

static LSGlobe.CoplanarPolygonOutlineGeometry.pack(value, array, startingIndex) → Array.<Number>
Core/CoplanarPolygonOutlineGeometry.js 122

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