I’m working with Three.js and using EdgesGeometry to render the edges of a cube. The cube itself is visible correctly, but the edges from the back side are also being rendered and appear on top of the cube, which I don’t want.
import * as THREE from “three”;
const scene = new THREE.Scene();
scene.background = new THREE.Color(0xffffff);
const camera = new THREE.PerspectiveCamera(
75,
window.innerWidth / window.innerHeight,
0.1,
1000
);
camera.position.set(3, 3, 3);
camera.lookAt(0, 0, 0);
const renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.BoxGeometry(1, 1, 1);
const material = new THREE.MeshBasicMaterial({
color: 0x00ff00,
depthTest: false,
});
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
const edges = new THREE.EdgesGeometry(geometry);
const line = new THREE.LineSegments(
edges,
new THREE.LineBasicMaterial({
color: 0x000000,
})
);
scene.add(line);
import { OrbitControls } from “three/examples/jsm/controls/OrbitControls.js”;
const controls = new OrbitControls(camera, renderer.domElement);
controls.update();
function animate() {
requestAnimationFrame(animate);
renderer.render(scene, camera);
}
animate();
window.addEventListener(“resize”, () => {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize(window.innerWidth, window.innerHeight);
});
