As someone who is new to Javascript, I am struggling to understand how the time argument functions within the animate function provided below. It seems that the animate function requires a time argument, but when called as a callback in setAnimationLoop, no argument is being passed in. Can anyone clarify this for me?
import * as THREE from './js/three.module.js';
let camera, scene, renderer;
let geometry, material, mesh;
init();
function init() {
camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 0.01, 10 );
camera.position.z = 1;
scene = new THREE.Scene();
geometry = new THREE.BoxGeometry( 0.2, 0.2, 0.2 );
material = new THREE.MeshNormalMaterial();
mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setAnimationLoop( animation );
document.body.appendChild( renderer.domElement );
}
function animation( time ) {
mesh.rotation.x = time / 2000;
mesh.rotation.y = time / 1000;
renderer.render( scene, camera );
}
