But surely you wouldn't try to emit that format directly, but rather some higher level scene description? Or even just a set of instructions for how to manipulate the UI to create the imagined scene?

I've seen this but producing Python scripts that you run in Blender, e.g. https://www.youtube.com/watch?v=x60zHw_z4NM (but I saw something marginally more impressive, not sure where though!)

My god that is an irritating video style, "AI woweee!"

Also the level of fault tolerance... if your pixels are a bit blurry, chances are no one notices at a high enough resolution. If your json is a bit blurry you have problems.

You can do "constrained decoding" on a code model which keeps it grammatically correct. But we haven't gotten diffusion working well for text/code, so generating long files is a problem.

Recent results for code diffusion here: https://www.microsoft.com/en-us/research/publication/codefus...

I'm not experienced enough to validate their claims, but I love the choice of languages to evaluate on:

> Python, Bash and Excel conditional formatting rules.

The rate of progress in ML this past year has been breath taking. I can’t wait to see what people do with this once controlnet is properly adapted to video. Generating videos from scratch is cool, but the real utility of this will be the temporal consistency. Getting stable video out of stable diffusion typically involves lots of manual post processing to remove flicker.

What was the big “unlock” that allowed so much progress this past year? I ask as a noob in this area.

Where do you want to start? The Internet collection and structuring the world's knowledge into a few key repositories? The focus on GPUs in gaming and then the crypto market creating a suite of libraries dedicated to hard scaling math. Or then the miniaturization and focus on energy efficiency due to phones making scaled training cost-effective. Finally the papers released by Google and co which didn't seem to recognise quite how easy it would be to build and replicate upon. Nothing was unlocked apart from a lot of people suddenly noticed how doable all this already was.

> you'll describe something and you'll get a full 3D scene, with 3D models, source of lights set up, etc. I'm always confused why I don't hear more about projects going in this direction. Controlnets are great, but there's still quite a lot of hallucination and other tiny mistakes that a skilled human would never make.

I think the bottleneck is data For single 3D object the biggest dataset is ObjaverseXL with 10M samples For full 3D scenes you could at best get ~1000 scenes with datasets like ScanNet I guess Text2Image models are trained on datasets with 5 billion samples

Oh, I don't know about that. Working in feature film animation, studios have gargantuan model libraries from current and past projects, with a good number (over half) never used by a production but created as part of some production's world building. Plus, generative modeling has been very popular for quite a few years. I don't think getting more 3D models then they could use is a real issue for anyone serious.

There has been massive progress in ML every year since 2013, partly due to better GPUs and lots of training data. Many are only taking notice now that it is in products but it wasn't that long ago there was skepticism on HN even when software like Codex existed in 2021.

> Has anyone come across a solution where model can iterate (eg, with prompts like "move the bicycle to the left side of the photo")? It feels like we're close. I feel like we're close too, but for another reason. For although I love SD and these video examples are great... It's a flawed method: they never get lighting correctly and there are many incoherent things just about everywhere. Any 3D artist or photographer…

From my very clueless perspective, it seems very possible to train an AI to use Blender to create images in a mostly unsupervised way.

So we could have something to convert AI-generated image output into 3D scenes without having to explicitly train the "creative" AI for that.

Probably much more viable, because the quantity of 3D models out in the wild is far far lower than that of bitmap images.

we're working on this if you want to give it a try - dream3d.com

You should put a demo on the landing page

just redid the ux and making a new one, but here's a quick example: https://www.loom.com/share/fa84ba92d7144179ac17ece9bf7fbd99

A seemingly off topic question, but with enough compute and optimization, could you eventually simulate “reality”? Like, at this point, what are the technical counters to the assertion that our world is a simulation?

There can be no technical counters to the assertion that our world is a simulation. If our world is a simulation, then hardware/software that simulates it is outside of our world and it's technical constitution is inaccessible to us.

It's purely a religious question. When humanity invented the wheel, religion described the world as a giant wheel rotating in cycles. When humanity invented books, religion described the world as a book, and God as a it's writer. When humanity invented complex mechanism, religion described the world as giant mechanism and God as a watchmaker. Then computers where invented, and you can guess what happened next.

Looks like I'm still good for my bet with some friends that before 2028 a team of 5-10 people will create a blockbuster style movie that today costs 100+ million USD on a shoestring budget and we won't be able to tell.

What I am really looking forward is some Star Trek style holodeck, but I guess we will start with it in VR headsets first.
