"Canvas2D is a HUGE addition to babylon.js. It is basically an entire 2D accelerated engine available out of the box. Indeed babylon.js is a full featured 3D engine, but the need to handle 2D content is often encountered when working on games or complex applications.
Canvas2D in a non HTML feature, 100% WebGL based, developed to serve the purpose of drawing, animating and interaction with 2D Content."
