During inference, our method takes a coarse triangle mesh as input and recursively subdivides it to a finer geometry by applying the fixed topological updates of Loop Subdivision, but predicting vertex positions using a neural network conditioned on the local geometry of a patch.

As such, we propose the direct perturbation of physical parameters that underly image formation: lighting and geometry.
