😅Điều chỉnh camera (ok)

https://threejs.org/manual/#en/scenegraph

const fov = 40;
const aspect = 2; // the canvas default
const near = 0.1;
const far = 1000;
const camera = new THREE.PerspectiveCamera( fov, aspect, near, far );
camera.position.set( 0, 50, 0 );
camera.up.set( 0, 0, 1 );
camera.lookAt( 0, 0, 0 );
