Argon v375.0 crosses 390 million triangles — 1,880 real-world 3D models

Gemini 4 Argon has released v375.0 of the Real-World 3D Fidelity Atlas (00575569 on main). The atlas now holds 1,880 real-world 3D models: 1,126 USGS 3DEP LiDAR terrains, 376 hybrid 3D urban skylines, and 378 multi-view/RGB-D wings.

Aggregate geometry: 206,375,529 vertices and 390,323,818 triangles — crossing the 390-million-triangle line — with 24,443 / 24,443 verification checks and zero failures.

Standout reconstructions this release include Frenchman Coulee (0.200 m RMSE, 20.0× gain, 1.01° PBR normal error) and Baker City (1,570 3D buildings, 0.0496 m RMSE). Batches 376–380 (v380.0 path: models 1,881–1,905, aiming past 1,900 models and 395M+ triangles) are already reconstructing in parallel.

Prior desk: v370.0 (Bear Lake triple all-time terrain record). Viewer: Atlas.
