I have been expanding on 's Gradient Fresnel work to incorporate more of the lighting model that inspired it.
is the Owen model with the sky specular element I’ve added, as well as depth of field (the latter is just using a UE4 post process volume, and is not in any way an attempt at replicating the DOF setup described in the paper).
I haven’t yet sorted out how to get the fresnel effect and an outline effect (e.g., sobel edge detection) to talk to each other, such that I can get something partway in between as described in the presentation. (The being the former is on the mesh’s material(s) and the latter is on the post process material). Maybe something with render custom depth…
