I ended up reading one of the referenced articles too since it captured my interest https://www.gamedeveloper.com/disciplines/fovo-a-new-3d-rend... all of this looks interesting. I would love to add these correction and similar to my game engine to experiment with it, but fovotec seems to have to be paid/contacted for. I might try and replicate what the author of the main article showed at the end. Does anyone know of any more references to the 3d rendering side of this topic?

Edit: Added words for clarity.
