Interesting. One of the diagrams suggests that the mesh is generated from the marching cubes algorithm but the geometry of the meshes shown above are clearly not generated in this way.

If they are using MC, does that mean they are actually generating SDFs? If so it would be nice if you could output the SDF rather than the triangle mesh.

Wow they really need to work on that first splash image[1]. All the assets there look hideous. [1] https://github.com/Tencent/Hunyuan3D-2/blob/main/assets/imag...

the assets look good as a starting point, they may even be used as background elements

> the object was on a rotating platform Isn't a static-object-rotating-camera basically a requirement for photogrammetry?

Why would that make a difference?

The OC mentioned "static lighting". If they meant static, while the platform was spinning, then the lighting would be inconsistent, because the object would change lighting with each photo. You would have to fix the lighting to the platform to spin with the object, while taking the pictures to get consistent lighting.

Generative AI is going to drive the marginal cost of building 3D interactive content to zero. Unironically this will unlock the metaverse, cringe as that may sound. I'm more bullish than ever on AR/VR.

AR/VR doesn't has a 3D model issue.

It has a 'why would I strap on a headset for stuff I can do without'

I will not starting meeting friends just because of the meta verse. I have everything I need already.

And even video calls with Whatsapp is alweird as f.

I think you’re being short sighted. Imagine feeding in your favorite TV shows to a generative AI and being able to walk around in the world and talk to characters or explore it with other people.

do you find it interesting talking to NPCs in games?

If I could talk to something at the level of Neuro-sama (https://www.twitch.tv/vedal987) I'd be very entertained and it's essentially a matter of time. Hell, I'd love to have something like this as an assistant application as well and I'm not a Cortana/Google Assistant/etc user.

I can only speak for myself, but a Metaverse consisting of infinite procedural slop sounds about as appealing as reading infinite LLM generated books, that is, not at all. "Cost to zero" implies drinking directly from the AI firehose with no human in the loop (those cost money) and entertainment produced in that manner is still dire, even in the relatively mature field of pure text generation.

I think the biggest issue with stable diffusion based approaches has always been poor compositional ability (putting stuff where you want), and compounding anatomical/spatial errors that gave the images an offputting vibe. All these problems are trivially solvable (solved) using traditonal 3d meshes and techniques.

The issue with composition is only a problem when you rely on a pure text prompt, but has been solved for quite a while by ControlNets or img2img. What was lacking was the integration with existing art tools, but even that is getting solved, e.g. Krita[1] has a pretty nice AI plugin.

3D can be a useful intermediate when editing the 2D image, e.g. Krea has support for that[2]. But I don't think the rest of the traditional 3D pipeline is of much use here, AI image generation already produces images at a quality that traditional rendering just can't keep up with, neither in terms of speed, quality or flexibility.

I think you fundamentally misunderstand what people use "slop" to describe. > Most human made art is slop too. I'm assuming you're using the term "slop" to describe low-quality, unpolished works, or works where the artist has been too ambitious with their skill level. Let me put it this way: Every piece of art that is made, is a series of decisions. The artist uses their lived experience, their tastes and their value…

> here's a human-made piece that I appreciate a lot I like your art. I'm glad you made it. What I like most is that it's fun to look at and think about which is what you say you intended. I hope I get to see more of your art. > To this point, I don't believe there's such a thing as "bad art" (all works have something to say about the artist!). As a classically trained oil painter, I know for sure there is bad art esp…

> I like your art. I'm glad you made it. What I like most is that it's fun to look at and think about which is what you say you intended. I hope I get to see more of your art.

Just to be clear, it's not my art.

you dont know which prompt activates the backdoor, how can you firewall it if you run the model in production?

3d asset generation is a use case that for most doesn’t need to run in production

"In production" in this case is a stand-in for "in any environment with access to sensitive stuff" which might just include GPUs, if what the attacker wanted was crypto processing grunt. Besides, if you're providing 3D asset generation as a service (which I can imagine most deployments of this sort of thing will be, at least for now) then it absolutely is running in production. The purpose of that production environment is entirely to run asset generation.
