SUMMARY:3D Reconstruction with Fast Dipole Sums
DESCRIPTION:Hanyu Chen, Bailey Miller, and Ioannis Gkioulekas (Carnegie Me
 llon University)\n\nWe introduce a method for high-quality 3D reconstructi
 on from multi-view images. Our method uses a new point-based representatio
 n, the regularized dipole sum, which generalizes the winding number to all
 ow for interpolation of per-point attributes in point clouds with noisy or
  outlier points. Using regularized dipole sums, we represent implicit geom
 etry and radiance fields as per-point attributes of a dense point cloud, w
 hich we initialize from structure from motion. We additionally derive Barn
 es-Hut fast summation schemes for accelerated forward and adjoint dipole s
 um queries. These queries facilitate the use of ray tracing to efficiently
  and differentiably render images with our point-based representations, an
 d thus update their point attributes to optimize scene geometry and appear
 ance. We evaluate our method in inverse rendering applications against sta
 te-of-the-art alternatives, based on ray tracing of neural representations
  or rasterization of Gaussian point-based representations. Our method sign
 ificantly improves 3D reconstruction quality and robustness at equal runti
 mes, while also supporting more general rendering methods such as shadow r
 ays for direct illumination.\n\nRegistration Category: Full Access, Full A
