directly training a NeRF on a single image is a terribly unconstrained problem that would lead to a volume that looks bad when the viewpoint changes. the gist of render + use diffusion model to refine is a great idea though and core to our method! the details of how to use the diffusion model for this refinement was the challenge, but once we figured that out it... just worked :)

Very cool! Can we tweak your algorithm a little to be seeded with a real photo from a single viewpoint?

it's a good idea :)
