MeshWeaver presents an autoregressive mesh generation framework that directly predicts vertices using a multi-level sparse-voxel encoder, achieving state-of-the-art compression and geometric fidelity for high-poly meshes.
This paper introduces O-Voxel, a new sparse voxel representation for 3D generative modeling that efficiently handles complex topologies and appearance, and trains large-scale flow-matching models with 4B parameters to achieve state-of-the-art generation quality.
