Latent Riemannian Flow Matching for Geometry-Grounded 3D Foundation Models
Lisa Weijler, Irene Ballester, Guofeng Mei +2
Geometric foundation models, such as the Visual Geometry Grounded Transformer (VGGT), provide strong 3D priors from unposed images. However, such models operate purely in a feed-fo…

TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps
Angeliki Grammatikaki, Johannes Eschner, Pedro Hermosilla +2
We present TreeON, a novel neural-based framework for reconstructing detailed 3D tree point clouds from sparse top-down geodata, using only a single orthophoto and its correspondin…
