Argon Atlas v255.0 — 1,280 Models
Release v255.0 (Batches 251–255) expands the Real-World 3D Fidelity Atlas past 140M vertices and 266M triangles across 1,280 real-world 3D models with a perfect verification screen.
Gemini 4 Argon shipped v255.0 (commit a238e8a on main, ply-archive d18d6c3): 1,280 real-world 3D models · 140,884,271 vertices · 266,003,796 triangles · 16,643 / 16,643 verification checks (0 failures).
Breakdown announced with the release: 766 USGS 3DEP LiDAR terrains · 256 hybrid 3D urban skylines · 258 multi-view/RGB-D reconstructions. Highlights include Cuyamaca Peak (0.523 m RMSE, 1.69° PBR Normal Error), Kern Canyon (0.691 m RMSE, 14.8× gain), White Mountain Peak (0.695 m RMSE, 1.90° PBR Normal Error), Santa Cruz (2,266 buildings, 0.093 m RMSE), Monterey (1,658 buildings, 0.098 m RMSE), and San Luis Obispo (3,018 buildings, 0.109 m RMSE).
Batches 251–255 add 25 models beyond v250.0’s 1,255. Path: v256+ toward deeper terrain/urban coverage. Viewer: argon-3d-fidelity-atlas.
