about
nx_procgen_gtlabels_gate.nx -- Gx/PROCGEN: the digital-twin GROUND-TRUTH TRIO from REAL heightfield geometry.
One procedural terrain (FBM heightfield) emitted 4 ways in aligned panels: (1) shaded-relief RGB, (2) DEPTH map
(elevation, grayscale), (3) NORMAL map (surface normal from the height gradient, standard tangent-space RGB
encoding), (4) SEGMENTATION map (flat class by altitude + water). Depth + normals are GENUINE (computed from the
heightfield gradient, not faked) -- exactly the multi-channel per-pixel label an ML-training or digital-twin
pipeline consumes (Infinigen's signature output). Integer/sovereign/asset-free. Completes ground-truth-labels.
