City-Mesh3R: Simulation-Ready City-Scale 3D Mesh Reconstruction from Multi-View Images
City-Mesh3R introduces a scalable framework for reconstructing high-fidelity 3D city-scale meshes directly from unordered image collections using a divide-and-conquer strategy. The method addresses limitations of existing NeRF and Gaussian Splatting approaches by producing watertight, simulation-ready meshes suitable for large urban scenes without prohibitive computational overhead.
