about

nx_worldgen.nx -- ★SOVEREIGN INFINIGEN, RUNG 1: procedural NATURE (operator 2026-07-08, sharing princeton-vl/ infinigen: "build a WORLD full of living people, animals, environments, weather"). Infinigen = seed->procedural photoreal 3D, NO ML, NO external assets -- EXACTLY our doctrine. This is the nature/"hello world" module: a seed grows a whole LANDSCAPE -- fBm terrain (grass/rock/snow by height+slope) + water (lakes/sea) + sky gradient + sun + procedural clouds + atmospheric fog. All INTEGER, sovereign, our own heightfield ray-marcher. Different seed = different world; a weather param retints sun/sky/fog (clear / sunset / overcast). license_tier: ORIGINAL
