I need assistance with removing the parameters widthSegments and heightSegments.
When I modify this line of code:
var tergeo= new THREE.PlaneGeometry(100, 100, 1, 1);
to:
var tergeo= new THREE.PlaneGeometry(100, 100, 0, 0);
The changes do not produce the desired result.
What is the correct approach to eliminate widthSegments and heightSegments in the following jsFiddle ?

let scene = new THREE.Scene();
let camera = new THREE.PerspectiveCamera(60, innerWidth / innerHeight, 1, 1000);
camera.position.set(0, 0, 10);
let renderer = new THREE.WebGLRenderer();
renderer.setSize(innerWidth, innerHeight);
document.body.appendChild(renderer.domElement);
let g = QuadGeometry(THREE.MathUtils.randInt(5, 10), THREE.MathUtils.randInt(5, 10));
let m = new THREE.LineBasicMaterial({color: "yellow"});
let quad = new THREE.Line(g, m);
scene.add(quad);
function QuadGeometry(w, h){
let pts = [
[0.5, 0.5],
[-0.5, 0.5],
[-0.5, -0.5],
[0.5, -0.5]
].map(p => {return new THREE.Vector2(p[0], p[1])});
let g = new THREE.BufferGeometry().setFromPoints(pts);
g.setIndex([0, 1, 2, 3, 0]);
g.scale(w, h, 1);
return g;
}
renderer.setAnimationLoop(() => {
renderer.render(scene, camera);
});
