SceneShift InteriorGS Bench (50 Scenes)

A spatial reasoning VQA benchmark built on 3D Gaussian Splatting (3DGS) reconstructions of real indoor scenes from the InteriorGS dataset.

Dataset Summary

• 50 indoor scenes from InteriorGS
• 129,362 questions across 13 question types
• 3,820 rendered images from diverse camera poses
• 4 camera motion patterns: around, linear, rotation, spherical
• 13 question types: object_size, object_distance_to_camera, object_pair_distance_center, relative_size, relative_distance, relative_distance_to_camera, mc, object_size_comparison_relative, object_size_comparison_absolute, object_pair_distance_center_w_size, object_pair_distance_vector, object_comparison_absolute_distance, object_comparison_relative_distance
