New 3D foundation model paper uses Riemannian flow matching to stay on the manifold

The paper Latent Riemannian Flow Matching for Geometry-Grounded 3D Foundation Models proposes a way to denoise in the latent space of VGGT so its 3D priors can be used more effectively.

The key technical move is to use Riemannian flow matching to keep the process on the manifold. The accompanying visual comparisons show context images, ground truth, and outputs against Gen3R and DepthSplat across multiple scenes, illustrating the geometry-grounded reconstruction quality.
