Minecraft Clone is a project I created for DCU module EE497 - 3D Interface Technologies.
It's an attempt at a browser-based clone of Minecraft. It is intended for entirely for academic use. In it, the user can load a basic scene of destructible voxels, navigate around the scene and destroy voxels by clicking on them. All objects are constructed from scratch in Javascript using OpenSceneGraph (Robert Sadleir's custom implementation of the OSG.js WebGL framework).
Written almost entirely in Javascript. It requires nothing more than a web browser to run. Try it on your phone!
