SUMMARY:Efficient Cone Singularity Construction for Conformal Parameteriza
 tions
DESCRIPTION:Mo Li, Qing Fang, Zheng Zhang, Ligang Liu, and Xiao-Ming Fu (U
 niversity of Science and Technology of China)\n\nWe propose an efficient m
 ethod to construct sparse cone singularities under distortion-bounded cons
 traints for conformal parameterizations. Central to our algorithm is using
  the technique of shape derivatives to move cones for distortion reduction
  without changing the number of cones. In particular, the supernodal spars
 e Cholesky update significantly accelerates this movement process. To sati
 sfy the distortion-bounded constraint, we alternatingly move cones and add
  cones. The capability and feasibility of our approach are demonstrated ov
 er a data set containing 3885 models. Compared with the state-of-the-art m
 ethod, we achieve an average acceleration of 15 times and slightly fewer c
 ones for the same amount of distortion.\n\nRegistration Category: Full Acc
