The authors present Codimensional MultiMeshing, a framework for editing related meshes while maintaining their correspondences. It represents meshes as nodes in a tree linked by containment maps, then propagates edits and updates the maps. Applications include UV seams and tetrahedral remeshing. In a TetWild reimplementation, 5,097 of 5,163 models met the 150 distortion threshold; it was slower than original TetWild.
Key insights
- A formal hierarchical representation with containment maps allows for systematic management and coherent correspondences between multiple embedded meshes of varying dimensions.
- Automated propagation of topological operations through 'extension' and 'restriction' significantly simplifies algorithm design and implementation for complex multi-geometry problems.
- Explicitly tracking embedded structures as distinct meshes within the multimesh enables features like topology preservation that are difficult or impossible with traditional tag-based methods.
