SurFlo

Feed-forward 3D surface reconstruction fusing multiple unposed images into a fixed-size global latent (K=128 tokens, ViT + Perceiver), then decoding surface points independently via per-point flow-matching ODEs at any resolution, with inference-time Gaussian-splatting render guidance. Across eight benchmarks (2-32 views) it beats VGGT, Gaussian Wrapping and NOVA3R on Chamfer Distance and F1.
