alt Hacker NewsI think only the part about blocks getting smaller as you go down and then doubling in size again is in the article. Will check.
I'm saying "presumably" because of points the article didn't spell out. Edit: I re-read and it doesn't talk about the very much non-cuboid blocks at the corners, or the pointed blocks at the core. Not in words, anyway. They're implied in the pictures.
If you want comments that build on this ... it's the triplets of quads that really bother me. They only appear at eight places on the surface of the planet, but it would mess with strategy in a strategy game (my own efforts were inspired by trying to create Civ on a true sphere) if routes between tiles are sometimes short-circuited. It would also distort house architecture in a sims-like, and mess up city grids if one of these triplet corners happens to be in the middle of your city, which would then go from having north-south and east-west streets to having ... six cardinal directions?
They do mention it:
> When it comes to placing block structures, there are two (2) edge cases that can throw a wrench into things:
> 1. The corners where three (3) sectors meet break the regular horizontal grid topology, since three (3) blocks meet at the corner instead of four (4)
> 2. Vertical shell boundaries break the regular vertical grid topology, since a block can have four (4) vertical neighbors instead of just one (1)
> This means that there are places on our planet where it’s impossible to define a box-shaped zone of blocks that corresponds to the block structure’s source zone. I could just detect and prevent structures from being placed at these locations, but I opted for a more general solution.
> Placing structures will now “work” everywhere, though it can get a little wonky around the problematic areas. Still, I prefer this to having dead zones where no structures can be placed at all.
