In procedural cave / dungeon generation, CELLULAR AUTOMATA (e.g. 4-5 rule) typically smooth which kind of initial input?
APre-built room templates only loaded once during init
BRandom binary fill (each cell wall with probability p)
CA finite-state machine of three states only at most
DManually drawn pixel art at exactly 1:1 scale always
Answer & Solution
Correct answer: B. Random binary fill (each cell wall with probability p)
Sebastian Lague + many tutorials: start with ~45% wall probability; iterate B5/S4 rule (cell becomes wall if ≥5 neighbours are wall, survives if ≥4). Yields organic caves.
