http://www.lab4games.net/zz85/blog/2014/09/08/rendering-lines-and-bezier-curves-in-three-js-and-webgl/

Sample code:

“ js
let geometry = new THREE.Geometry();
let x0 = 0, y0 = 0;
let x1 = 0, y1 = 10;
let x2 = 10, y2 = 10;
let curve = new THREE.QuadraticBezierCurve3(
new THREE.Vector3(x0, y0, 0),
new THREE.Vector3(x1, y1, 0),
new THREE.Vector3(x2, y2, 0)
);
geometry.vertices = geometry.vertices.concat(curve.getPoints(100));
let material = new THREE.LineBasicMaterial({ color : 0xff0000, linewidth: 2 });
let ellipse = new THREE.Line(geometry, material);
scene.add(ellipse);
