HRsR: Hierarchical Rotation System Reconstruction
Ruiqi Cui, Cem AkarsubaÅı, Emil Toftegaard Gæde +3
Surface reconstruction from point clouds remains challenging when both geometric fidelity and topology control are required. Rotation System Reconstruction (RsR) reconstructs trian…

Learning to Build Shapes by Extrusion
Thor Vestergaard Christiansen, Karran Pandey, Alba Reinders +3
We introduce Text Encoded Extrusions (TEE), a text-based representation that expresses mesh construction as sequences of face extrusions rather than polygon lists, and a method for…

Surface Reconstruction Using Rotation Systems
Ruiqi Cui, Emil Toftegaard Gæde, Eva Rotenberg +2
Inspired by the seminal result that a graph and an associated rotation system uniquely determine the topology of a closed manifold, we propose a combinatorial method for reconstruc…
