Generating Artist-Like 3D Mesh Topology via Nearest-Vertex Vector Fields
2 days ago
- TriFlow is a generative approach for producing compact 3D meshes with artist-like triangle topology from signed distance field inputs.
- Key insight: representing mesh topology as a nearest-vertex vector field (NVF) over the surface, using a latent flow-matching model to synthesize this field conditioned on input geometry.
- Mesh extraction involves clustering surface regions with the generated NVF and using constrained QEM mesh simplification with topology-aware optimization.
- Results show stronger generalization, improved topology quality, 90% lower Chamfer Distance, and 8× speedup over state-of-the-art methods.
- TriFlow can target different topology budgets while preserving the input geometry.
