Andreas Bærentzen (Technical U niversity of Denmark)\n\nInspired by the seminal result that a graph and a n associated rotation system uniquely determine the topology of a closed m anifold, we propose a combinatorial method for reconstruction of surfaces from points. Our method constructs a spanning tree and a rotation system. Since the tree is trivially a planar graph, its rotation system determines a genus zero surface with a single face which we proceed to incrementally refine by inserting edges to split faces. In order to raise the genus, sp ecial handles are added in a later stage by inserting edges between differ ent faces and thus merging them. We apply our method to a wide range of in put point clouds in order to investigate its effectiveness, and we compare our method to several other surface reconstruction methods. It turns out that our approach has two specific benefits over these other methods. Firs t, the output mesh preserves the most information from the input point clo ud. Second, our method provides control over the topology of the reconstru cted surface.\n\nRegistration Category: Full Access, Full Access Supporter \n\nLanguage Format: English Language\n\nSession Chair: Michael Wimmer (TU Wien) URL:https://asia.siggraph.org/2024/program/?id=papers_693&sess=sess112 END:VEVENT END:VCALENDAR
