Eikonal Fields for Refractive Novel-View Synthesis
Published 2 Feb 2022 in cs.GR and cs.CV | (2202.00948v3)
Abstract: We tackle the problem of generating novel-view images from collections of 2D images showing refractive and reflective objects. Current solutions assume opaque or transparent light transport along straight paths following the emission-absorption model. Instead, we optimize for a field of 3D-varying Index of Refraction (IoR) and trace light through it that bends toward the spatial gradients of said IoR according to the laws of eikonal light transport.
