Circle, Sphere and Dome Generator
Block circles, ellipses, spheres and domes for building, thin, thick or filled, layer by layer with block counts and /fill commands.
Sizes from 1 to 256 blocks.
A thin outline can step diagonally; a thick one never does.

Commands
A block id, like stone or white_concrete.
40 /fill commands, one for each row. They build the shape centred on where they run, its bottom layer at that height: put them in a data pack function, or paste them into command blocks.
fill ~-3 ~ ~-10 ~3 ~ ~-10 stone
fill ~-5 ~ ~-9 ~-3 ~ ~-9 stone
fill ~3 ~ ~-9 ~5 ~ ~-9 stone
fill ~-6 ~ ~-8 ~-5 ~ ~-8 stone
fill ~5 ~ ~-8 ~6 ~ ~-8 stone
fill ~-7 ~ ~-7 ~-6 ~ ~-7 stone
fill ~6 ~ ~-7 ~7 ~ ~-7 stone
fill ~-8 ~ ~-6 ~-7 ~ ~-6 stone

How the game works it out
| Which blocks | A block is part of the shape when its middle is inside the circle, ellipse or sphere that fills the size exactly |
| Odd and even sizes | An odd size has one middle block; an even size has its middle between two blocks |
| Thin and thick | A thin outline keeps every block with an empty side next to it and can step diagonally; a thick outline also counts empty corners, so it never steps diagonally |
| Domes | A dome is the top half of a sphere twice its height; a hollow dome is open underneath |
| Commands | One /fill per row of blocks, written relative to the place they run from, so a data pack function builds the shape around the player |
| Checked in the game | Seven shapes (circles, an ellipse, spheres, an ellipsoid and a dome) were built in the game with the commands, each with exactly the block count the tool shows |
