SUMMARY:Surface Reconstruction Using Rotation Systems
DESCRIPTION:Ruiqi Cui, Emil Toftegaard Gæde, and Eva Rotenberg (Technical 
 University of Denmark); Leif Kobbelt (Visual Computing Institute, RWTH Aac
 hen University); and J. Andreas Bærentzen (Technical University of Denmark
 )\n\nInspired by the seminal result that a graph and an associated rotatio
 n system uniquely determine the topology of a closed manifold, we propose 
 a combinatorial method for reconstruction of surfaces from points. Our met
 hod constructs a spanning tree and a rotation system. Since the tree is tr
 ivially a planar graph, its rotation system determines a genus zero surfac
 e with a single face which we proceed to incrementally refine by inserting
  edges to split faces. In order to raise the genus, special handles are ad
 ded in a later stage by inserting edges between different faces and thus m
 erging them. We apply our method to a wide range of input point clouds in 
 order to investigate its effectiveness, and we compare our method to sever
 al other surface reconstruction methods. It turns out that our approach ha
 s two specific benefits over these other methods. First, the output mesh p
 reserves the most information from the input point cloud. Second, our meth
 od provides control over the topology of the reconstructed surface.\n\nReg
