about

nx_indoor.nx -- ★R8 of the Infinigen ladder: INDOOR scenes (their CVPR'24 Infinigen-Indoors track). A room shell (floor/ceiling/4 walls) + procedural FURNITURE placed by a CONSTRAINT SOLVER (rule-based positions + collision rejection + in-bounds) -> a valid, seed-varied furnished room, rendered by an integer AABB interior raycaster (rays from a camera inside the room hit the nearest box; shaded by face + a ceiling light). The constraint-solved layout is the intellectual core (their paper is about realistic arrangement). license_tier: ORIGINAL
