My another small production, with motif of Minecraft. This time I have created Minecraft world in spherical coordinates. This construction is very simple, that is why it cannot have things like caves, and another drawback - the cubes closer to poles are deformed. I have decided not to use shaders because I don't want the flat shaded surfaces (the flat shader consume more memory) and after few tests it looks like rendering the scene using GL 1 was bit faster than GL 2.
I was thinking about game using this kind of generated world, but so far I don't have reasonable ideas.
