SUMMARY:Reach For the Spheres: Tangency-aware surface reconstruction of SD
 Fs
DESCRIPTION:Silvia Sellán (University of Toronto), Christopher Batty (Univ
 ersity of Waterloo), and Oded Stein (University of Southern California)\n\
 nSigned distance fields (SDFs) are a widely utilized implicit surface repr
 esentation that has applications in various fields such as computer graphi
 cs, computer vision, and applied mathematics. Despite their frequent use, 
 traditional methods such as Marching Cubes and its variants often overlook
  fundamental properties of SDFs, resulting in mesh reconstructions that ex
 hibit oversmoothing and feature loss. To address this, we propose a novel 
 method based on a key insight: each SDF sample corresponds to a spherical 
 region, and the surface represented by the discrete SDF has critical prope
 rties with respect to each sphere. Leveraging this understanding, our meth
 od formulates an energy that gauges the degree of violation of tangency co
 nstraints by a proposed surface. We then employ a gradient flow that minim
 izes our energy, starting from an initial triangle mesh that encapsulates 
 the surface. The algorithm yields superior reconstructions, surpassing the
  quality of previous methods, even with sparsely sampled SDFs. Our approac
 h provides a more nuanced understanding of SDFs and offers significant imp
 rovements in surface reconstruction.\n\nRegistration Category: Full Access
