# Point-Track Residual Consistency

VGGT-Diff is a geometry-routed multi-view diffusion framework that uses a frozen VGGT-Ω to transform source-view features together with 3D points and confidence into query-aligned conditions via a confidence-aware Visual Geometry Router, injects them into a pretrained Wan2.1-I2V-14B video diffusion model, and regularizes predicted-clean residuals along reliable 3D tracks with Point-Track Residual Consistency; trained on only 980 DL3DV scenes, it ranks first in PSNR, LPIPS and DreamSim and second in SSIM on 6,188 DL3DV-Benchmark targets, and first in LPIPS and DreamSim with second-place PSNR on zero-shot Mip-NeRF 360.
