I used Daz3D for most of them. The one I posted today was AI-generated at NightCafe (a lot quicker but a lot more hit and miss).
If you mean actual 3D models, then you could recreate them from scratch in Daz3d (available at daz3d.com). It's free (although it's easy to then spend a lot on it for additional clothes, props, hair, poses) and relatively easy to learn (there are a few tutorials and a really good forum), and you'll get basic human 3D figures that are highly customisable. For the faces, there is software (sadly not free, but they have frequent sales) that will transfer 2D faces to a 3D character. If you just want them to look like they're 3D, you can quickly use Nightcafe (you get five credits free) to create a picture using your 2D version as your start image, and provide a suitable text description (though, like me, you might find some words you want to use are censored). That will generate 4 pictures, based on your original picture, but the AI randomness can be a bit annoying. Worth a quick try though. I think you can install the underlying Stable Diffusion on your computer directly, if your computer's sufficiently high spec, so you can get round the censorship issues, but try it first just to see if it's what you want. Just as an example, the Daz3d images above took me an hour or so each. For the Nightcafe AI one, I didn't even need a start-up image. I basically just typed "Alyson Hannigan in black underwear by Adam Hughes" and the AI generated it in a few seconds, so if you don't really need 3D-ness, just the illusion of 3D, then I'd go the Nightcafe route. NB Other AI generators are available, and there's a post about them somewhere on this forum. Having said that, Daz3d does offer a lot more control, and if you want to use your characters time after time then you might want to go that route. Also it supports multiple characters a lot better (if your computer has the power). You could do the same thing in Poser, but I've never tried that. Hope that helps. If not, I'd try googling, or maybe other forum users can provide suggestions.
You're welcome. Good luck with it, whatever you decide to do, and if you have any further questions, please feel free to ask them.
Hey bobbydavros, I'm just curious. I don't know anything about 3d, but I have always been a fan. Actually, I'd love to be able to do something like that. I looked into Daz a little, but it feels like typically you'll end up having to buy a lot of stuff made by others. While I can see how that saves a lot of time, that really doesn't fascinate me. That made me understand why 3d artists I have seen tend to reuse the same body model/face for years, with just minor adjustments to hair and body proportions. Makes sense: once you have bought something, you make the most use of it and you are not inclined to buy another female model I guess. How long did it take to make one of those pictures? Hours? Days? And how long did it take for you to be able to pull something like that off? Weeks? Months?
Hey SeriousBrainDamage, you're right, with Daz3D you can end up buying a lot of stuff made by others (although occasionally some people offer it free, such as the Little Mermaid figure). I'm not sure if 3d artists tend to reuse the same body model/face for years because of the expense or because they're happiest with that particular figure or they're just lazy. It's pretty easy to change the body shape (there's some free body morphs that come with it initially). It's a matter of hours to make one of the pictures, although I might go through a few iterations that can take it into days (and sometimes the hard work is finding the outfits to begin with). I think it was weeks more than months before I could pull it off (although in real time it was months since I just dabbled in it occasionally). It didn't take long at all to print out a single figure, I was doing that right away, but the posing, props, clothing, lighting and scenery take a while (and depending on your computer, the rendering itself can take ages).
I've had a look at daz far too daunting for me. I'm an old school artist best with a pencil and sheet of paper lol. I had a go at Photoshop editing a photo
