While working on a project in three.js to create a ring, I encountered an issue with lighting. The camera setup is fine, but I'm facing difficulties with lighting. Below is my code snippet:
<script src="three.js"></script>
<script src="https://threejs.org/examples/js/controls/OrbitControls.js"></script>
<script src="https://threejsfundamentals.org/threejs/../3rdparty/dat.gui.module.js"></script>
<script>
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
const renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
const color = 0xFFFFFF;
const intensity = 1;
const light = new THREE.DirectionalLight(color, intensity);
light.position.set(10, 10, 10);
light.target.position.set(-5, 0, 0);
scene.add(light);
scene.add(light.target);
document.body.appendChild( renderer.domElement );
let controls = new THREE.OrbitControls(camera, renderer.domElement);
controls.target.set(0, 0, 0);
controls.rotateSpeed = 0.5;
controls.update();
camera.position.z = 5;
const geometry = new THREE.RingGeometry( 1, 3, 32 );
const material = new THREE.MeshBasicMaterial( { color: 0xffff00, side: THREE.DoubleSide } );
const mesh = new THREE.Mesh( geometry, material );
mesh.receiveShadow = true;
mesh.castShadow = true
scene.add( mesh );
function animate() {
requestAnimationFrame( animate );
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.01;
renderer.render( scene, camera );
}
animate();
</script>
I've experimented with changing the light source to AmbientLight and SpotLight, but unfortunately, they didn't work as expected. My priority is to display the 3D shape, so any type of light source that can help achieve this goal is acceptable.
