Main
Description
https://adventofcode.com/2021/day/19
To correlate all the scanner readings this program selects the first scanner to be "correct". All other scanners will be oriented relative to the first scanner. As each scanner's location is fixed it will be queued to be compared to all the uncorrelated scanner outputs. Scanning in this order ensures no pair of scanners is compared more than once.
Synopsis
- main :: IO ()
- start :: [[Coord3]] -> [(Coord3, Set Coord3)]
- assemble :: [[Coord3]] -> [(Coord3, Set Coord3)] -> [(Coord3, Set Coord3)]
- match :: Set Coord3 -> [Coord3] -> Maybe (Coord3, Set Coord3)
- prefilter :: [Coord3] -> [Coord3]
- reorient :: [Coord3] -> [[Coord3]]
- faces :: Coord3 -> [Coord3]
- rotations :: Coord3 -> [Coord3]
