about

nx_scene_render.nx -- render ONE (SceneWorld, SceneEntity) pair under any style (exceed-ladder R0; pairs with nx_scene_contract.nx). Side-elevation view: the camera slice is the entity's anchor row. Each screen column maps to a world cell; ground height -> screen row; terrain filled below, sky above; the synthetic human stands ON the ground at the anchor (insertion is physical, not a paste). Style law (from the contract): the SAME entity + world render under all four styles; only the named tables change the art: REALISTIC -- continuous elevation gradient + slope shading ANIME -- 5 cel bands, saturated, bright sky, eye dots CARTOON -- 3 flat bands, dark outline around figure and band edges VN -- sunset-gradient backdrop, terrain as far silhouette, portrait-scale sprite with eyes Tier 0: nx_scene_quickstart(world_seed, human_seed, style, path) -- one call -> a P6 PPM scene on disk. license_tier: ORIGINAL
