ArchWorld comprises 396 in-the-wild 3D landmarks across eight geographic regions, derived from MegaScenes. It features rich metadata and metric-scale dense ground-truth reconstructions to enable disaggregated evaluation.
The benchmark evaluates 3D foundation models on reconstruction quality, revealing geographic performance disparities driven by architectural style and scene complexity rather than just data representation.
