A-Frame: VR in the Browser
A-Frame is a web framework for making VR games and environments in the browser. The last language you would expect to code VR in would be HTML, but A-Frame challenges your feeble expectations and has you code a game slap in the middle of an HTML file.
A-Frame, being a web framework, loves hand-holding and easy-peasy tutorials, so you can get started with A-Frame HERE.
This framework will blow away anything you’ve experienced before. It’s attempt is akin to bringing a full VR experience to your Google Cardboard.
