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 IoR and trace light through it that bends toward the spatial gradients of said IoR according to the laws of eikonal light transport.
