This document discusses setting up a basic virtual reality scene in Three.js. It creates a WebGL renderer, perspective camera, and device orientation and VR controls to handle input. It also initializes a VR effect for the renderer to display the scene in virtual reality.

23. // Create a renderer
var renderer = new THREE.WebGLRenderer();
// Create a camera
var camera = new THREE.PerspectiveCamera(fov, aspect,
near, far);
// Setting up SP controller
var spControls =
new THREE.DeviceOrientationControls(cameara);
spControls.connect();
// Setting up VR controller and effect
var controls = new THREE.VRControls(camera);
var effect = new THREE.VREffect(renderer);
effect.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
セットアップはたったこれだけ
