about

nx_treegen.nx -- ★SOVEREIGN INFINIGEN: procedural VEGETATION (trees). A seed grows a UNIQUE tree by recursive branching (an L-system-style growth stack): trunk -> branches -> sub-branches -> leaf clusters, with phototropism (upward bias) + seeded angle/length/count variation. Branches = tapering CAPSULES, leaves = green spheres. Self-contained SDF + integer ray-march with a bounding-sphere early-reject (so hundreds of parts stay fast). No ML, no assets. Different seed -> different tree. license_tier: ORIGINAL
