Hi,<p>I've been learning WebGL and THREE.js in the last few weeks, and thought building a Voxels demo might be interesting and within my reach.<p>Commands are pretty much the same as in Minecraft, but there's a twist: you can place a "magic" blue block. If the next stone block is in the same row as a blue block, a whole line of blocks will appear between the blue block and the stone block you just placed. This way you can, hopefully, place large amounts of blocks more easily than in Minecraft, thus making the building of large structures quicker. The obligation to put blocks one by one in Minecraft kind of frustrated me, and I thought a feature that would make construction quicker might be great in a voxels demo.<p>Enjoy and have a nice day!
