Creating a new basic line material using THREE.js often does not yield the desired result.
I am looking for an easy way to draw 3D lines with different colors and widths, suitable for a rotating scene.
I have looked into various methods like Windows & Angle, but most of them do not work well in 3D or come with their own set of issues.
The challenge arises because WebGL line primitives are always rendered as 1px wide lines, making it difficult to create wider lines. However, with three.js, there is a solution available by rendering fat or wide lines based on triangles using the classes LineGeometry, LineMaterial, and Line2.

This code snippet is using three.js R107

import * as THREE from 'three';
import { MeshLine, MeshLineMaterial} from 'three.meshline';
createThickLine(point1, point2, color) {
const geometry = new THREE.Geometry();
geometry.vertices.push(
new THREE.Vector3( point1.X, point1.Y, point1.Z ),
new THREE.Vector3( point2.X, point2.Y, point2.Z )
);
const line = new MeshLine();
line.setGeometry( geometry );
const material = new MeshLineMaterial({color});
const mesh = new THREE.Mesh( line.geometry, material );
this.scene.add( mesh );
