camera.position.z = 1;const scene = new THREE.Scene();const geometry = new THREE.BoxGeometry( 0.2, 0.2, 0.2 );
const material = new THREE.MeshNormalMaterial();const mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );const renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( width, height );
renderer.setAnimationLoop( animation );
document.body.appendChild( renderer.domElement );// animationfunction animation( time ) {mesh.rotation.x = time / 2000;mesh.rotation.y = time / 1000;renderer.render( scene, camera );}
</script><style></style>
