What is BabylonJS

BabylonJS is primarily a rendering engine, it has a whole slew of other features which makes it a pretty good browser based game engine. My personal usage of using this is me finding a really awesome feature an wrapping it in an abstraction/proxy that my platform would use. The mesh is central to the application, models and the such, so I created a EngineMesh which is just an extended object of the Mesh. This allows me to "shadow" the mesh and add mode details relating to my platform that would not other wise be available to my games.

Also by making all mesh/model creation go through a factory, I can alway return an EngineMesh and alway have a layer of abstraction away from the models. This allows for me to use this abstraction in other aspects of the engine, pointer picking to another one. Wrapping the mesh with more metadata data allows for special logic to happen during a pointer trigger, sending selection events that can then be used to display other UI details. So long story short, I am able to create custom logic with raw events from the BabylonJS engine.

This is just some of what I use BabylonJS, and this is just the start to my BabylonJS series.
