Tech support
Apple are supporting the standard too, so we can (hopefully!) expect to see it cropping up in Safari on Macs, iPhones and iPads sometime (though probably not soon) - and Opera are testing their own version, so the only holdout is Microsoft.
So sit back, crank up your latest browser, and check out these demos - if you think you can do better, go for it: there are some hints and tips on how at the end.
01. 3 Dreams of Black
3 Dreams of Black
This piece of WebGL features the song Black by Danger Mouse and Daniel Luppi
3 Dreams of Black is a semi-interactive film by Chris Milk, using technology developed by Google and others, featuring the song Black from the album ROME by Danger Mouse and Daniel Luppi, with Norah Jones and Jack White. It takes you through three separate dreams, mixing 2D and 3D computer graphics with video. It works best on Chrome. Read net magazine's report on the project here.
02. Flight of the Navigator
Flight of the Navigator
Flight of the Navigator is rendered in real-time in JavaScript and WebGL
Created by the Mozilla Audio API team, the Flight of the Navigator is a non-interactive music video rendered in real-time in JavaScript and WebGL, with Twitter and Flickr integration. You can read all about how it was created on David Humphrey's blog.
03. No Comply
No Comply
No Comply from the Mozilla Audio API team has an '80s video game vibe
No Comply is another WebGL demo from the Mozilla Audio API team, mixing video and graphics with a very 1980s-computer-game-meets-the-Matrix vibe. Because it uses certain new non-standard Firefox features for the audio, unfortunately it currently only works in Firefox. You can read more about how it was created in this article by Paul Rouget at hacks.mozilla.org.
04. 3Dtin
3Dtin
3Dtin is great for beginners as it is easy to get started with
Most tools for building 3D content are hard to use - expert-friendly but beginner-hostile. 3Dtin is easy to get started with, letting you create shapes with a natural voxel-orientated (think 3D pixel) approach. And once you've created your design, you can export it to reality using 3D printing services from i.materialise.
05. Chemdoodle
Chemdoodle
Chemdoodle lets you see chemical structures in 3D
As you'd expect with a new technology, there are a lot of people using WebGL to do cool demos, and fewer real tools. Chemdoodle is an exception to this. iChemLabs, a scientific visualisation company, has put together tools for viewing molecules in web pages; this demo page lets you pick one of a number of medicines and see a 3D representation of its chemical structure in the browser.
