SimplePolylineGeometry

new SimplePolylineGeometry

A Geometry that represents 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.

Parameters:

Name	Type	Argument	Description
`options.positions`	Array	<optional>	An array of Cartesian3 defining the positions in the polyline as a line strip.

Throws:

DeveloperError : At least two positions are required.

Example

// A polyline with two connected line segments
var geometry = new SimplePolylineGeometry({
  positions : ellipsoid.cartographicArrayToCartesianArray([
    Cartographic.fromDegrees(0.0, 0.0),
    Cartographic.fromDegrees(5.0, 0.0),
    Cartographic.fromDegrees(5.0, 5.0)
  ])
});

Members

attributes :Object

An object containing GeometryAttribute properties named after each of the true values of the VertexFormat option.

See:

Geometry#attributes

boundingSphere :BoundingSphere

A tight-fitting bounding sphere that encloses the vertices of the geometry.

indices :Array

Index data that, along with Geometry#primitiveType, determines the primitives in the geometry.

primitiveType :PrimitiveType

The type of primitives in the geometry. For this geometry, it is PrimitiveType.LINES.
