One of the extremely clever minds behind the much-used and loved WebGL library Three.js is a chap who goes by the name of AlteredQualia. He’s just published another fantastic WebGL demo, this time showcasing real-time reflections and motion blur. If you don’t already follow him on Twitter, I strongly suggest you start doing so.
These kind of effects were considered cutting edge in console games just a few years ago, and now we’re seeing them natively in our browsers. That’s really awesome!
