GEAR treats geometry as a memory address: sparse correspondence attention cuts ATE by 80.3% for minute-long camera-controlled video generation
The work introduces GEAR, which avoids fusing history into a persistent global 3D representation and instead uses per-frame geometry to build token-level history-to-target correspondences, treating geometry as an explicit address for visual memory; Geometric Correspondence Attention then sparsely injects only geometrically matched historical features, while an Invisible Octree rejects projectable but occluded correspondences, reporting state-of-the-art visual quality, camera control, and revisit consistency on DL3DV-Evaluation and WorldScore-Static and enabling minute-long generation.
