We have built in France a WebGL 3d realtime engine named BabylonJS. It has been made to support all WebGL compatible platforms such as Chrome, Firefox, Opera, IE11 on the desktop as well as on Firefox OS, Android & Windows 8.1 devices. We will see 2 main points in this session. First, we’ll share some of the things we’ve learned while building it: how to track and reduce the garbage collector, how to pay attention to the performance and how to handle touch on all devices. Then, we’ll see how to use these frameworks to build your own 3d applications & games for the web! Be ready to read some code.
