Artifact Adventure

Artifact Adventure is a dynamic Three.js demo that transforms curated art from The Met Museum's API into an immersive 3D experience directly in your browser.

Features

In Artifact Adventure, users:

• Navigate a first-person 3D virtual art exhibit with WASD and mouse controls.
• Render different virtual environments instantly.
• Lighting, shadows, textures, and reflections respond in real-time to their virtual environments.
• View artwork from The Met Museum API rendered in 3D.
  
  

Instructions

Interacting with Artifact Adventure is easy and intuitive:

• Start the demo with a left-click on your mouse.
• Move around the 3D environment with your WASD keys.
• Look at your surroundings with your mouse.
• Jump with the spacebar.
• Pause the demo by pressing ESC.
  
  

Object-Oriented Design Principles

Each Three.js component handles a specific part of WebGL to render high-performance 3D graphics in your browser.

Artifact Adventure is composed of the following components:

• Camera
• Scene
• Lights
• Mesh Objects
• Environment Map
• Renderer
  
  

The Experience

The Experience class manages the complete experience by:

1. Accepting a HTML canvas DOM element as an argument,
2. Instantiating all necessary component classes and,
3. Handles persistent animation via a requestAnimationFrame loop.

// Experience.js
this.debug = new Debug();
this.sizes = new Sizes();
this.time = new Time()
this.scene = new THREE.Scene();
this.camera = new Camera()
this.environment = new Environment();
this.renderer = new Renderer()

this.time.on('tick', () => {
  this.update();
})

// Experience.js
requestAnimationFrame(this.update);

const time = performance.now();
const delta = ( time - prevTime ) / 1000;

velocity.x -= velocity.x * 10.0 * delta;
velocity.z -= velocity.z * 10.0 * delta;

this.camera.controls.moveRight( - velocity.x * delta );
this.camera.controls.moveForward( - velocity.z * delta );

this.renderer.instance.render( this.scene, this.camera );
this.renderer.update();

The update() class function listens for WASD key presses to trigger and update camera movement while re-rendering in real-time to simulate movement throughout the 3D environment.

Note: Excerpted for length & clarity.

The Environment

The Environment class handles the creation and rendering of the lighting, environment map and mesh objects.

setEnvironmentMap = () => {
  this.environmentMap = this.textureLoader.load('/textures/environmentMap/00.png');
  this.environmentMap.mapping = THREE.EquirectangularReflectionMapping;
  this.environmentMap.colorSpace = THREE.SRGBColorSpace;
  this.scene.background = this.environmentMap;
}

setFloor = () => {
  this.floorGeometry = new THREE.CircleGeometry( 100, 64, 0, 2 * Math.PI );
  this.floorGeometry.rotateX( - Math.PI / 2 );

  const floorTexturePathURL = '/textures/floor/dirt/color.jpg'
  const floorTexture = this.textureLoader.load(floorTexturePathURL);
  floorTexture.repeat.set(20, 20);
  floorTexture.wrapS = THREE.RepeatWrapping;
  floorTexture.wrapT = THREE.RepeatWrapping;

  const floorMaterial = new THREE.MeshBasicMaterial( { map: floorTexture } );
  
  const floor = new THREE.Mesh( this.floorGeometry, floorMaterial );
  this.scene.add(floor);
}

setLight(){
  this.light = new THREE.HemisphereLight( 0xeeeeff, 0x777788, 2.5);
  this.light.position.set( 0.5, 1, 0.75 );
  this.scene.fog = new THREE.Fog( 0xffffff, 0, 750 );
  this.scene.add(this.light);
  //...
}
