Profiled; very interesting information. Tried to build a sphere legitimately (7x7x7) as 300 or so blocks isn't too hard to gather. I'm cheating and making a giant dome in the ocean, however. Probably like 40x40x20
But now i really want to go a step further and do donuts, eggs/ovals, waves, warps and bends. Basically a program that can calculate the voxels layer per layer and make build plans from any 3d shape. Is such a thing already existing out there? Google is not really helpful in this regard.
