20 Impressive Examples for Learning WebGL with Three.js
By now you have probably heard about Three.js - a library which makes working with 3D in the browser easy. With it, you can create the building blocks of 3D modeling - cameras, meshes, lights and more, and apply animations on them. Three.js can draw a scene using a Canvas element, SVG, CSS3D or WebGL.
In this article, you will find a collection of demos, tutorials and resources that will inspire you to learn more about the library.
Experiments and Demos
The impressive demos that you see below are made with the Three.js library and WebGL as a renderer. It is possible to use WebGL directly, but choosing Three.js makes development easier and results in only a fraction of the code. Here are some of the things that are possible with the library:
Nucleal is a WebGL experiment, powered by the Three.js. It breaks photos down into thousands of particles that are transformed by physics. You can choose any combination of photo, speed and effects. The animations run smoothly which is even more impressive.
Lights is an amazing visual experience, powered by Three.js, which syncrhonizes colors and shapes to music. You fly through a scene filled with colorful shapes, which you can interact with by clicking. Headphones are recommended.
3. Just A Reflektor
“Just A Reflektor” is an interactive film that lets you cast a virtual projection on your computer screen by holding up your mobile device in front of your computer’s webcam. That way, you control all of the visual effects in the experience by moving your phone or tablet through the physical space around you. See some of the amazing effects on the tech page, and the behind the scenes video.
4. Arms Globe
Arms Globe is a visualization experiment which overlays the world trade of small arms and ammunition on top of a model of the earth which you can rotate in 3D space. You can filter the data set by years and types of ammunition. The visualization is very impressive and runs smoothly.
5. Google Street View Hyperlapse
This experiment downloads Google Streetview data between two destinations, and turns it into an animation of the trip. You can pause and take a look around, or you can drag a target on the map on the top-right which the camera will follow. Give it a few minutes to load or watch this video to see it in action.
6. Find Your Way To Oz
This is a promotional website for the Oz the Great and Powerful movie. It combines beautiful artwork with HTML5 and WebGL into immersive experience. It takes place in the circus from the beginning of the movie. You can interact with the environment and use your web cam.
7. Google Zeitgeist
Google's Zeitgeist for 2012 included a WebGL powered world map which presented the search trends and important events from the past year. Click the "Watch the year in review" button to see it.
9. Cube Slam
Cube Slam is my favorite Three.js powered game from this list. It is a spin of the classic pong game, but moves it into 3D space. You can play against your friends or computer-controlled bear. The game uses WebRTC so you see a video of your friend's webcam. For a behind the scenes, read through this blog post by one of the creators.
11. Chrome World Wide Maze
This is a Chrome Experiment by Google that lets you turn any web page into a 3 dimensional maze through which you move a ball. What is even cooler, is that the ball is controlled from your smartphone.
HelloRun is a WebGL game powered by Three.js that puts you in the hull of a spaceship and forces you to find your way by jumping through hurdles. The game has great visuals and progressively speeds up and becomes more difficult.
13. Hello Racer
Hello Racer is an impressive visualization of a Formula 1 racing car, powered by WebGL and Three.js. It features life-like reflections and shadows. You can even drive it around with the WASD keys.
14. 360 Car Visualizer
This is another experiment that features detailed car visualizations. This time you can choose the car model and color. The colors are applied dynamically and all the textures are updated to match.
15. Google Maps Cube
Google Maps Cube is a game that presents you with a 3D maps cube. Your job is to navigate a ball through the city and reach checkpoints.
16. CSS3D Periodic Table
This is an impressive demo of Three.js. Instead of WebGL, this experiment uses CSS3D to render the chemical elements boxes. You can choose between four layouts: table, sphere, helix and grid.
17. WebGL Globe
The WebGL Globe is a visualization experiment that, similar to the arms globe, presents data overlayed on a globe floating in 3d space. This example is centered around population by city, but you can see versions with different data sets here.
Obsidian is a WebGL demo that synchronizes floating shapes and colors to music. Although there is a slider at the bottom, this is not a video - the effects are generated in real time.
19. Indra's Net
This demo presents a multidimensional web of raindrops that reflect each other and the world around them. Even though a very large number of objects is involved, the rendering is still quite fast.
20. Planet Maker
Planet Maker is a web app powered by WebGL and Three.js that lets you create real or imaginary planets. You can choose from several surface texture options, tweak the lighting and atmosphere, add or remove clouds, upload your own imagery, or wrap a ring around them.
Bonus: WebGL Nyan Cat
Frankly, no collection of WebGL resources is complete without a nyan cat. Enjoy!
