Chapter 37: LineSegmentsGeometry

Core Idea

A series of vertex pairs, forming line segments.

This is used in LineSegments2 to describe the shape.

Key Concepts

• isLineSegmentsGeometry : boolean (readonly): This flag can be used for type testing.

Code Examples

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

• What it demonstrates: Typical usage of LineSegmentsGeometry.

Methods

Method	Description
.applyMatrix4( matrix : Matrix4 ) : LineSegmentsGeometry	Applies the given 4x4 transformation matrix to the geometry.
.fromEdgesGeometry( geometry : EdgesGeometry ) : LineSegmentsGeometry	Setups this line segments geometry from the given edges geometry.
.fromLineSegments( lineSegments : LineSegments ) : LineSegmentsGeometry	Setups this line segments geometry from the given line segments.
.fromMesh( mesh : Mesh ) : LineSegmentsGeometry	Setups this line segments geometry from the given mesh.
.fromWireframeGeometry( geometry : WireframeGeometry ) : LineSegmentsGeometry	Setups this line segments geometry from the given wireframe geometry.
`.setColors( array : Float32Array	Array.<number> ) : LineSegmentsGeometry`
`.setPositions( array : Float32Array	Array.<number> ) : LineSegmentsGeometry`
