Here’s a recent demo made by researchers at Nvidia trying to render the most detailed, realistic scene possible using AI tech to a small degree -mostly as asset compression, but also in material modeling beyond what direct approaches can currently handle in real time: https://m.youtube.com/watch?v=0_eGq38V1hk

Here’s a video from a rando on Reddit conveniently posted today after playing around for an afternoon: https://www.reddit.com/r/aivideo/comments/1n1piz4/enjoy_nano...

The Nvidia team carefully selected a scene to be feasible for their tech. The rando happened to select a similar-ish scene that is largely well suited for game tech.

Which scene looks more realistic? The rando’s by far. And, adding stylization is some AIs are very well established as being excellent at.

Yes, there are still lots of issues to overcome. But, I find the negativity in so many comments in here to be highly imbalanced.

that rando's one looks like fucking garbage like a bunch of shitty B roll footage from an AI generated advertisement for some kind of pharmaceutical, the space and layout of the world clearly is constantly shifting and makes no sense. just generate a fucking map we already know how to do this, tracking geometry is an EASY problem for computers, don't force some AI shit to try to do it for some reason.

There's something so unsettling about that 2nd link you posted, and I don't mean from an "AI is impressive" POV (I think it looks like absolute garbage but will probably continue improving bit by bit). There's something even in the still frames which scratches my brain in a very unpleasant way, it's hard to describe the sensation. The closest thing is "disgust", maybe it's a uncanny valley type of effect.

Also, how are these 2 comparable at all? Obviously the video looks more "realistic", the first one is obviously a game demo of some kind and is stylized, whereas the latter looks like a terrible travel agency ad.

Don't focus on the emotional context of the scenes. Look at the physical content. They are both contain stonework, plants and a human. They are both large, detailed scenes lit by strong sunlight and a bright sky. As far as rendering technology requirements go, they are very similar.

There is strong discontinuous motion effect because of how the video tech is based on a sequences of "first frame, last frame" inputs spliced together. There are a couple seconds where her behavior gets uncanny valley --particularly her hands on the door. Wouldn't be a concern in an unrealistic video game. But, would be in a this-realistic game regardless of the tech. And, there is a very slight warble in the fine details. But, you have to really look for those to distinguish them from MPEG artifacts.

I expect what a lot of people here are feeling when they watch the video is disgust based 90% or more just on the fact that the video was AI generated :/
