Ultra3D

Ultra3D is an efficient 3D generation framework that uses Part Attention, a geometry-aware localized attention mechanism, to generate high-fidelity 3D meshes at 1024 resolution with up to 6.7× speedup. The two-stage approach leverages VecSet representation for coarse layout generation followed by per-voxel latent refinement within semantically consistent part regions.
