20个令人印象深刻的例子学习Three.js实现WebGL

1. Nucleal

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.

2. Lights

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 thescenes
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.

8. Ironbane

Ironbane is a massively
multiplayer online game powered by WebGL and Three.js. You can collect items, interact with other players and explore the open world. The game follows a retro style inspired by Minecraft and runs smoothly. The game is open
source and both the client and server side are written in JavaScript. You can play without opening an account, so you can quickly try it for yourself.

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.

10. HexGL

HexGL is a futuristic,
fast-paced racing game built using HTML5, JavaScript and WebGL, with the help of Three.js. It is a tribute to the original Wipeout and F-Zero series. It is a graphically heavy game, approaching the level of desktop games from a few years ago. Luckily, you
can lower the level of detail before playing. Here
is a video from the game author explaining how he made the game.

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.

12. HelloRun

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.

18. Obsidian

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!
