e·jec·ta, noun – debris that is ejected during the formation of an impact crater
Ejecta is like a Browser without the Browser. It's specially crafted for Games and Animations. It has no DIVs, no Tables, no Forms – only Canvas and Audio elements. This focus makes it fast.
Many HTML5 Games run out of the box, or with minimal modifications – with better performance, better sound support, Game Center integration and more.
While Ejecta works nicely with straight forward Canvas animations, it grew out of a project to make the Impact Game Engine work natively on the iPhone. Chances are your Impact games run without modification – apart from controls and screen size – on Ejecta.
Older Ejecta versions (then called iOSImpact) implemented a lot of hacks and shortcuts to make it work. Ejecta mimics the HTML5 APIs more closely and thus works with a variety of Canvas libraries, including ThreeJS.
Ejecta runs on all iOS 8.0 or newer devices that support the armv7 or arm64 instruction set and run: the iPhone4S and newer as well as all iPads starting from the 2nd generation. It supports the retina resolution of all devices and screen sizes
