SUMMARY:3D Reconstruction with Fast Dipole Sums
DESCRIPTION:Technical Papers\n\nHanyu Chen, Bailey Miller, and Ioannis Gki
 oulekas (Carnegie Mellon University)\n\nWe introduce a method for high-qua
 lity 3D reconstruction from multi-view images. Our method uses a new point
 -based representation, the regularized dipole sum, which generalizes the w
 inding number to allow for interpolation of per-point attributes in point 
 clouds with noisy or outlier points. Using regularized dipole sums, we rep
 resent implicit geometry and radiance fields as per-point attributes of a 
 dense point cloud, which we initialize from structure from motion. We addi
 tionally derive Barnes-Hut fast summation schemes for accelerated forward 
 and adjoint dipole sum queries. These queries facilitate the use of ray tr
 acing to efficiently and differentiably render images with our point-based
  representations, and thus update their point attributes to optimize scene
  geometry and appearance. We evaluate our method in inverse rendering appl
 ications against state-of-the-art alternatives, based on ray tracing of ne
 ural representations or rasterization of Gaussian point-based representati
 ons. Our method significantly improves 3D reconstruction quality and robus
 tness at equal runtimes, while also supporting more general rendering meth
 ods such as shadow rays for direct illumination.\n\nRegistration Category:
