Trying to evaluate AI model generation (feddit.org)

Not trying to flood printables and co with more AI but honestly curious.

I am a person that has no sense for aesthetics whatsoever. In a creative process even less so. This would help me out im some situations. All functional parts j do in freecad.

A thread about myminifactory I asked about some ai site examples to evaluate the model quality. For example, do they know how to avoid overhangs if possible etc.

It got downvoted.

For real: what are some tested ai generators for stl?

EDIT: people are dming me links because (I assume) they don't want to admit they are not completely against ai. That is a healthy atmosphere right there. I agree that ai is taking a bad path right now but the tool itself shouldn't be discarded as a whole. You people are acting like calculators are bad because they let your mind rot. My grandfather was one of those. Simple answers are almost always wrong or incomplete. Think!

I cant do art

What's a good AI to do it for me?

lmao

[–] prenatal_confusion@feddit.org -1 points 1 day ago

Nit art but aesthetics. Similar but not the same.

And since AI is a stochastic machine that falls perfectly into its scope. Doesn't have to be "true" as in a correct answer but plausible eg similar to other models.

[–] GreenKnight23@lemmy.world 1 points 1 day ago

I suck at creating things

how can I steal ideas in the most complicated way and make them seem like I did them?

your comparison of AI to calculators is simple and wrong. your perception of your grandfathers position on calculators is also wrong.

in studies it was found that students that had access to calculators performed worse on tests that banned their use. so yes, calculators made people more error prone and less likely to successfully calculate for themselves. the reason for this being far more related to AI than you probably imagine.

the human brain learns through patterns and long term repetitions. it's similar to how machine learning happens. multiple failures compound together to form a coherent strategy and skill. AI(LLM)'s are trained in the same way.

so, in essence, by using an AI to generate based off of stolen content it's similar to using a calculator for your brain. you're robbing yourself of the opportunity to grow and expand your horizons as a creator, and you're supporting a system of theft that only diminishes the hard work and efforts of those it stole from.

You're getting downvoted because AI is causing so much damage and ruining so many things. People still using AI are just adding to the problem and continuing to legitimize the bullshit.

If you truly want to learn aesthetics, read some books, take some classes, get some practice. Learn a new skill!

[–] prenatal_confusion@feddit.org -4 points 2 days ago (1 children)

I disagree. Obviously ...

I think ai can be a useful tool for some very specific and well outlined tasks. We need to solve a lot of problems like energy and resource usage to make it sustainable at a small scale and don't feed the bubble and by extension the repercussions it will have on the world economy. And even if this doesn't pan out to be a viable tool for modeling I live by the principal that I need to know what I am talking about before I dismiss it.

And yes, the most common argument against that stance is "so to have an opinion about fascism you need to be an fascist?". No, but I need to read and learn about it nevertheless. This is my learning.

We need to solve a lot of problems like energy and resource usage to make it sustainable at a small scale and don’t feed the bubble and by extension the repercussions it will have on the world economy.

Just a few tiny little details to work out, to do "some very specific and well outlined tasks". And while those things are being worked on, which may or may not be solvable, real and actual damage is being done now. But hey, who cares right?

FFS, I bet it's the first time you are outraged about any issue. Maybe because it's affecting the prices of the hardware you want to buy. We are constantly mining this planet for resources that won't replenish, mistreating the so called onset developed countries or anybody that we can really to get ahead as a nation and personally too and we call it capitalism and free market. But now it's bad. Now it's personal.

It must be nice to know where to go before you explored the path and don't waste any resources on the way. Good on You. That must be why we live in such a just and developed world. Spoiler: we don't.

So just accept the fact that things that we and I'm this case you don't like and that we have to tolerate them anyways. Stop pushing your opinion at all cost and annoy anybody that you could have won over on the way.

I'm not the person you were talking to but why don't you take your own advice in your own post and

Stop pushing your opinion at all cost and annoy anybody that you could have won over on the way

AI is not a good or effective solution for replacing art. Talentless hacks think it's a game changer. Its clear with your arguments that you desperately want to replace artists with slop machines that churn out garbage. Clearly it's not well received by the majority of people. Instead of mindlessly doubling down on overhyped and under-delivering technology, go take that mental energy and use it to learn how to model. Otherwise everyone will rightfully clown on you.

Also, I just want to encourage you to actually do real research about what AI is and how it works. Your original post compared AI to the calculator and you accuse those who warn about AI use as being similar to those who warned not to use calculators. Calculators always get the right answer. They are precise. AI is not able to be precise. It doesn't understand it's outputs or it's inputs. AI is in absolutely no way comparable to calculators. You highlight your ignorance with this.

[–] prenatal_confusion@feddit.org -2 points 1 day ago

Regarding calculators: I meant that a new technology is always met with resistance. Rightfully or not is another subject. That was my point. Not ai adoption equals calculator adoption.

Regarding my opinion and winning over people: I responded to comments that were hostile (my perception). For me that's something else than trolling under comments. But hey that is another topic I really don't want to get into.

Regarding understanding: I am absolutely open to get educated if I got things wrong. What do You mean by AI being something else in principal than a algorithm that searches good next steps for a task while comparing it to previously learned content as a goal while incorporating the prompt? I understand it as an n dimensional vector field that looks for weights and tries to produce something resembling the prompt. For images that mostly enough (if you don't want to replace artists as in creativity, although taking work away from them). For text answers asking for facts that is horrible as we all know. Plausible is not enough there and the concept is fundamentally flawed.

I just looked up stochastic and you are right it's the wrong word. I can't think of a better one. If You can please let me know.

I hope this comments shows you that I am able to reasonably converse and am not, at all costs, picking fights.

I tried Meshy and Trellis and Hitem. Next I'll try printmon.

Hitem has the best free option and portrait mode. Made some great busts.

Meshy looked great if cartoony with its model 6, but only let me download from model 4, which was a surprise and made monsters.

Trellis was in between and I ran out of huggingface tokens quickly.

I'd use hitem all day but not interested in paid subscriptions for my passing hobby. Hoping Bambu is handy with printmon again, though I expect it may be proprietary.

Also, all needed some cleanup, Bambu could fix slice and print but not adjust details and cuts. Started with Blender but the interface is hard for a CAD person. Switched to using Meshmixer, which works great, and just using Bambu to do a final fix of the stl before slice. Make solid is a helpful tool in Meshmixer if you get a good looking but imperfect stl, but you have to be careful to avoid losing detail.

Thanks for the info!

@prenatal_confusion @T3CHT imagine how unfair #AI is to CAD designers with a human touch like those in #3DPrinting who have spent hours on a single project some projects it takes them weeks but if you want to use ai for example history based machine learning error recognition that’s something I can agree to that’s shared history as a community

[–] T3CHT@sh.itjust.works 0 points 1 day ago

I have been paid for and paid for CAD and other impacted engineering products including software. AI is unfair... How?

I can see some issues with copyright, and I acknowledge it will upset economies. But being able to 'automate' photo to 3d, and so many other tools that enable me so much to do things that wouldn't have happened before, it's unimaginable to many around me. Change is scary, strap in.

[–] prenatal_confusion@feddit.org -2 points 2 days ago

As is cad software to people that did technical drawings. As cars are to horses and ... So on.

Have you seen: https://github.com/KoStard/ForgeCAD

[–] prenatal_confusion@feddit.org 2 points 2 days ago (1 children)

I have not but it looks very interesting! I tried openscad but couldn't get far for the lack of skills. I'll try this one.

[–] HelloRoot@lemy.lol 2 points 2 days ago (1 children)

check out the llm benchmarks as well down below

[–] prenatal_confusion@feddit.org 2 points 2 days ago

Ah completely missed that

[–] db0@lemmy.dbzer0.com 2 points 2 days ago (1 children)

The bambulabs generator, particularly with the hunuan 3.0 model is really good. I'm using it for custom boardgame minis.

[–] T3CHT@sh.itjust.works 2 points 2 days ago (1 children)

Thanks, I'll try printmon next. Any hidden limits or fees?

[–] db0@lemmy.dbzer0.com 3 points 2 days ago

It's free, but you need to be contributing models and stuff to get a lot of usage, although the monthly free amount is plenty for basic usage
