How tall is a dome?
A half sphere is about half as tall as it is wide: a dome of 31 has 16 layers, because the middle layer of an odd diameter belongs to the dome. Enter a smaller height for a flatter dome or a larger one for a taller, egg-shaped dome, and the generator stretches the curve to fit.
Is a hollow dome open at the bottom?
Yes. The hollow dome is a shell without a floor, so it can sit on a wall, a tower or the ground. Filled counts the whole half sphere, for example for a hill or the blocks you dig out for a domed cave.
How do I put a dome on a round tower?
Give the dome the same diameter as the tower. With thin outlines on both, the first layer of the dome is the same ring as the tower wall, so you can build it directly on top of the wall or let the top layer of the wall be the first layer of the dome.
How do I build a glass dome underwater?
Build the shell in glass from the bottom ring up, then remove the water inside: soak it up with sponges, or fill the space with sand or gravel and dig it out. A thin shell is enough, because water cannot flow through a corner where two blocks only touch at an edge.
Should a dome have an odd or an even diameter?
Odd diameters are centred on one block, even ones on 2×2 blocks. Match the tower or room below and its doors: odd for openings 1 or 3 blocks wide, even for 2 or 4. The Odd/Even button switches between the two.
