hackernews weirdness has forced this roundabout way of replying to you about a thread from a bit ago...

i stumbled on your post about eye tracking needs for a relative dealing with MS.

i have some previous experience working with the tobii 4c and the 5 using more off-the-shelf solutions, as well as the more 'true medical grade' side of the tech, and may have some recommendations and learnings to share.

i have temporarily added a way to contact me into the about section of my profile. once i hear from you, or in about a week, i'll clear that out.

drop a line if you're interesting in discussing.

There’s work done around DeepSDF that do latent space diffusion but you end with a solid geometry suitable for 3D printing.

Would love to get away from photogrammetry the day splatting gets good enough

Doubtful they'll be optimized for games. I guess if by indie you mean unoptimized then maybe...you still don't get rigs or animation.

I mean, at that point you could just make a 2d game with the input images.
