OVGGT achieves constant-cost streaming for 3D geometry reconstruction

Researchers have introduced OVGGT, a novel framework designed for reconstructing 3D geometry from streaming video with constant memory and compute costs. This training-free approach addresses the limitations of previous models that suffered from growing memory usage over time. OVGGT employs techniques like Self-Selective Caching and Dynamic Anchor Protection to manage the KV cache and preserve geometric accuracy, enabling processing of arbitrarily long videos within a fixed VRAM budget.
