Eikonal Fields for Refractive Novel-View Synthesis. (arXiv:2202.00948v3 [cs.GR] UPDATED)

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.
