LineGeometry

A chain of vertices, forming a polyline.

This is used in Line2 to describe the shape.

Code Example

const points = [
	new THREE.Vector3( - 10, 0, 0 ),
	new THREE.Vector3( 0, 5, 0 ),
	new THREE.Vector3( 10, 0, 0 ),
];
const geometry = new LineGeometry();
geometry.setFromPoints( points );

Import

LineGeometry is an addon, and must be imported explicitly, see Installation#Addons.

import { LineLineGeometry2 } from 'three/addons/lines/LineGeometry.js';

Constructor

new LineGeometry()

Constructs a new line geometry.

Properties

.isLineGeometry : boolean (readonly)

This flag can be used for type testing.

Default is true.

Methods

.fromLine( line : Line ) : LineGeometry

Setups this line segments geometry from the given line.

line

The line that should be used as a data source for this geometry.

Returns: A reference to this geometry.

.setColors( array : Float32Array | Array. ) : LineGeometry

Sets the given line colors for this geometry.

array

The position data to set.

Overrides: LineSegmentsGeometry#setColors

Returns: A reference to this geometry.

.setFromPoints( points : Array.<(Vector3|Vector2)> ) : LineGeometry

Setups this line segments geometry from the given sequence of points.

points

An array of points in 2D or 3D space.

Returns: A reference to this geometry.

.setPositions( array : Float32Array | Array. ) : LineGeometry

Sets the given line positions for this geometry.

array

The position data to set.

Overrides: LineSegmentsGeometry#setPositions

Returns: A reference to this geometry.
