Why Does My Three.js Cube Texture Appear Different from the Original Image?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm working with Three.js to apply an image as a texture on a cube, but the texture displayed on the cube doesn't match the actual image's appearance.

I tried setting the renderer's output color space and adjusting the texture encoding with the following lines:

JAVASCRIPT
renderer.outputColorSpace = THREE.SRGBColorSpace;

Despite these changes, the cube's texture still doesn't look right. Below is a full code snippet that reproduces the issue. Any suggestions on what might be causing the discrepancy would be greatly appreciated!

Here’s the code:

JAVASCRIPT
import ‘./style.css’; 

import * as THREE from ‘three’; 

//html element 
const bookSection = document.querySelector(‘.book’); 

//variables 
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(
    75,
    window.innerWidth / window.innerHeight,
    0.1,
    1000
);

//adding renderer  
const renderer = new THREE.WebGLRenderer({ alpha: true, antialias: true });  
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.outputColorSpace = THREE.SRGBColorSpace;
bookSection.appendChild(renderer.domElement);

//adding lights  
const ambient = new THREE.AmbientLight(0xffffff, 0.5);
const directionalLight = new THREE.DirectionalLight(0xffffff, 0.5);
directionalLight.position.set(0, 0, 6);
// scene.add(ambient);
// scene.add(directionalLight);

//adding textures  
const textureLoader = new THREE.TextureLoader();
const texture = textureLoader.load(‘src/images/front.png’, (tex) => {
    tex.encoding = THREE.sRGBEncoding;
});

//adding boxes  
const geometry = new THREE.BoxGeometry(3.5, 5, 0.5);
const material = new THREE.MeshBasicMaterial({
    map: texture,
});
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

camera.position.z = 6;

function animate() {
    //animation here
    // Rotate all the cubes in the scene
    cube.rotation.x += 0.01;
    cube.rotation.y += 0.01;
    renderer.render(scene, camera);
}

renderer.setAnimationLoop(animate);

Thanks in advance!!

Fixing Texture Color Space Issues in Three.js

I've identified a few issues in your code that might be causing the texture appearance discrepancy:

Main Issues

You're using an outdated property tex.encoding = THREE.sRGBEncoding which has been deprecated in newer versions of Three.js
The texture's color space isn't being set correctly

Solution

Here's how to fix your texture loading code:

JAVASCRIPT
const textureLoader = new THREE.TextureLoader();
const texture = textureLoader.load('src/images/front.png', (tex) => {
    // Use colorSpace instead of encoding
    tex.colorSpace = THREE.SRGBColorSpace;
});

The encoding property has been replaced with colorSpace in recent Three.js versions. This change ensures proper color space handling between your texture and the renderer.

Additional Recommendations

Enable the lights: Your lights are commented out, which means they won't affect the scene. If you're using MeshBasicMaterial, this won't matter, but if you switch to materials that respond to lighting (like MeshStandardMaterial), you'll need to uncomment these lines:

JAVASCRIPT
scene.add(ambient);
scene.add(directionalLight);

Consider using MeshStandardMaterial: If you want more realistic rendering with lighting effects:

JAVASCRIPT
const material = new THREE.MeshStandardMaterial({
    map: texture,
    roughness: 0.7,
    metalness: 0.0
});

Set the texture's color space immediately after loading:

JAVASCRIPT
const texture = textureLoader.load('src/images/front.png');
texture.colorSpace = THREE.SRGBColorSpace;

These changes should help ensure that the texture displayed on your cube matches the actual image's appearance by properly handling the color space throughout the rendering pipeline.
