That's absolutely fantastic! Given the status of all of the social media, I assumed the game was dead and source lost forever. Instead we get the game in active development and completely open!
What library is the user using? It doesn't look like anything I've seen so far and he doesn't say anything about the environment he's using to create his game, so it's not easy to follow.
'Most of the rendering code for these guides will be written using my own personal rendering library, which is essentially a wrapper around OpenGL, where I abstract away the OpenGL calls or group together common OpenGL functionality into a single renderer function, to make the game code easier to manage. Anyone who understands OpenGL should have no problem translating my native renderer code back into OpenGL, and in some instances I will provide the OpenGL calls in these guides.'
So tired of these technically voxel engines but not at all the voxels I remember. Anyone remember Delta Force or Ken Silverman's Voxlap? Those are voxel engines. These Minecraft clones may use the data structure of voxels however they lack the beauty of a true voxel engine. (I think Delta Force faked some of it's voxels, but I digress.)
