As I delve into learning three.js, I came across some examples worth exploring. One specific code snippet I attempted to execute can be found here. Unfortunately, all I saw was a blank black screen.
To troubleshoot, I adjusted the three.js source to my local directory. Additionally, I made changes to the material code below because I didn't possess the crate texture.
var material = new THREE.MeshStandardMaterial({metalness: 0, roughness: 0.5});
material.color.setHex(0xc23560)Here is some code along with detailed explanations:
let camera, scene, renderer;
let mesh;
// Call the necessary functions
initialize();
animate();
// Initialize the scene
function initialize() {
camera = new THREE.PerspectiveCamera(70, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.z = 400;
scene = new THREE.Scene();
// Add a point light to the scene
light = new THREE.PointLight(0xffffff, 1, 1000);
light.position.set(300,300,300);
scene.add(light);
// Create a box geometry and apply material to it
let geometry = new THREE.BoxBufferGeometry(200, 200, 200);
let material = new THREE.MeshStandardMaterial({
color: 0xc23560,
metalness: 0,
roughness: 0.5
});
mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
renderer = new THREE.WebGLRenderer();
renderer.setPixelRatio(window.devicePixelRatio);
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
// Handle window resizing
window.addEventListener('resize', onWindowResize, false);
}
// Adjust camera aspect ratio on window resize
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize(window.innerWidth, window.innerHeight);
}
// Animate the scene
function animate() {
requestAnimationFrame(animate);
mesh.rotation.x += 0.005;
mesh.rotation.y += 0.01;
renderer.render(scene, camera);
}body {
overflow: hidden;
margin: 0;
}<script src="https://threejs.org/build/three.min.js"></script>After some tinkering, I finally discovered the issue - the container I was using is actually made of metal, and I had incorrectly positioned the light source.
