Is there a way to asynchronously load multiple textures in three.js using a callback function?

Bringing in a single texture with a callback is a simple task, for instance:

var loader = new THREE.TextureLoader();
var texture1 = loader.load("https://i.imgur.com/UiTMJzv.png", process);

//executed only once texture1 is loaded
function process(){

}

But how do I go about loading multiple textures asynchronously (and not one after the other) and make sure a processing function is only triggered once all textures have finished loading?

Answer №1

If you want to handle loading textures in Three.js, you can leverage the power of THREE.LoadingManager:

const manager = new THREE.LoadingManager( function() {

    // This callback is triggered once both textures are loaded

} );

const loader = new THREE.TextureLoader( manager );
const texture1 = loader.load( 'texture1.png' );
const texture2 = loader.load( 'texture2.png' );
