Well this happened quicker than I expected

Funny how "Faster than expected!" is almost a meme, here and in r/collapse at the same time.

Abstract:

>DreamFusion has recently demonstrated the utility of a pre-trained text-to-image diffusion model to optimize Neural Radiance Fields (NeRF), achieving remarkable text-to-3D synthesis results. However, the method has two inherent limitations: (a) extremely slow optimization of NeRF and (b) low-resolution image space supervision on NeRF, leading to low-quality 3D models with a long processing time. In this paper, we address these limitations by utilizing a two-stage optimization framework. First, we obtain a coarse model using a low-resolution diffusion prior and accelerate with a sparse 3D hash grid structure. Using the coarse representation as the initialization, we further optimize a textured 3D mesh model with an efficient differentiable renderer interacting with a high-resolution latent diffusion model. Our method, dubbed Magic3D, can create high quality 3D mesh models in 40 minutes, which is 2x faster than DreamFusion (reportedly taking 1.5 hours on average), while also achieving higher resolution. User studies show 61.7% raters to prefer our approach over DreamFusion. Together with the image-conditioned generation capabilities, we provide users with new ways to control 3D synthesis, opening up new avenues to various creative applications.

Can I please get my head around text to image advancing so quickly? This is a lot.

no, and the whole field of AI will only get faster and faster from here on...that's the whole point of the singularity.

Advancements happening too fast to predict what's next, too fast to keep up.

You're right. Once these advancements get on the radar of the public as a whole.... things will get crazy. Future Shock anyone? We're really not built to understand exponential growth, even people on this sub. I remember you saying text-video would follow quickly after Dalle-2 dropped and people here were saying 5-10 years! The next couple of years are going to be WILD.

haha yeah man I wasn't joking around when I said that :P

its only gonna get faster. 2023 may be the tipping point imo.

Timelines are getting shorter and shorter, at least it feels that way. I've recently come around to AGI in 2029, but this year it feels like AGI might happen sooner. 2025 was the year things would get weird, but that could be next year! I'm on this sub and r/Futurology all the time and I'm having a hard time keeping up! I fear the rest of the decade is going to be destabilizing. The 20s are going to be a trip, the decade started with a once-in-a-century global pandemic! How will it end?

it's just a complexity/dimensionality issue. with 3d images, the training and diffusion principles are the same but your matrix gets one more dimension and dataset has to be of different nature. but since we don't have such datasets for training, i think these ppl somehow used the 2d trained model to create output in a dummy 3d space. i've done 3d modeling/rendering before and the challenge is just huge. this is too early but it's gonna mature so soon like everything else we've seen.

just wait for AI to publish more computer science research papers and just outdo itself, we just sit and enjoy the show. deepmind's AI already improved on matrix multiplication a few weeks ago, something humans couldn't do in 50+ years.

Wait WHAT?!

sorry i meant wait for AI to start publishing research papers and peer reviewing with other AI models.

Just the thought of AI publishing its own research papers is INSANE.

This is a lot what the early 2d models looked like, hyped to see this so early

Hey but guys…. telling r/futurology that AGI coming in 2028 is crazy!

That's incredible. NVIDIA has been absolutely nailing it recently.
