Game with girls scanned with 3D photogrammetry

[Mikah_zulu]

Hello f95zone! First post here. I'm experienced programmer & game developer for ten years at least but was absolutely out of the adult games section.

I'm looking for a feedback ragarding to adult games that contains 3D scans of real nude people (girls, in particular). I doubt about the legality and propriety of real people scans usage since I haven't found anything similiar on this forum and even web.

Feels like I'm obssesed with the idea of creating interactive game that involves 3D people scans with hyper-realistic realtime-render visuals.

Core gameplay cycle example:

1. Select a girl or group of girls
2. Play mini-games or complete the dialogue to unlock the next phase of seduction
3. Keep playing till full nudity / various sexy poses / free-roam camera controls.

Here is some examples of test scene I built:

I understand that platforms such as steam or even itch.io is not the targets for this. But I'm also do not want to deal with sh*thole adult commercial platforms. I just wish to make it for free to avoid the legal issues. Is there a greenling for this stuff here?

I'm looking for a feedback ragarding to adult games that contains 3D scans of real nude people (girls, in particular).

So, something more complicated to make than regular 3D, with results that will not necessarily be better since it will still depend on your capability to configure the game engine for it to provide a "real life"-like feeling ; and of course the capability of the game engine itself to do so.

I doubt about the legality and propriety of real people scans usage [...]

Well, it's really easy, it's totally and perfectly legal. Being understood that this can only be done if you have a full scan of the real person, what is something that you can't obtain without the consent on the said real person.
Anything else wouldn't be "3D scans of real nude people", but 3D projections of a 2D representation of a real nude person, that is something totally different and mostly illegal.

Here is some examples of test scene I built:

Censored... on a piracy forum dedicated to adult and porn games... really ?

What happens if the game use a non existent 3d model but gives free customization and the ability to put any 2d representation of anyone in 3D?

This kind of feeling mainly comes from the realization that you looking at person living somewhere on the planet. That is the main thought.

Yes, this is what I'm doubt about.

You mean wrapping the real face photo around 3D model like it is done in NBA2K23? It is a hard work to make it look "real" with even acceptable results. Here I'm talking about static quality 3D models of real people.

This kind of feeling mainly comes from the realization that you looking at person living somewhere on the planet.

Knowing that it's the 3D representation of a living person will not make a shitty rendered figure feel more real. It's the opposite, I'll expect the 3D representation to be way more living than usual.
And must be said that it's not what your screenshots achieve. Of course they are great, but unless they are supposed to represent a silicon sex doll, there's few problems.

 

[Meaning Less]

This kind of information is irrelevant to the end user. Regardless of how you acquire your models they are still just 3D models after scanned.
You can also use motion capture to speed up the animation process but they are still animations.

In fact many AAA games already use both these technologies to create their models and then people rip these models to make porn stuff, so it is nothing new.

In other words, regardless of how your creation process is done the only thing that matters is the end result. So just leave the results speak for themselves.

In the end it's all pixels, yes. The idea itself is not pretending to be revolutional. I've tried to find something similiar with no luck and it looks like a taboo to real people representation in adult games.

So just leave the results speak for themselves.

Bet you're right.

I thought people on this website were less shitty, sir Cletuzz, but I thought wrong. I apologize for the harsh reception you've received thus far.

Personally, I have no idea how this works but I do like the result. If it is easier to create and work with an asset this way or is otherwise significantly more realistic, it's definitely worth exploring. It could be that someone else is also working on this (maybe even the legacy porn industry for their VR content), so you could try joining forces with them. That would help you acquire consenting real-life models to work with/from. If it's not the whole body then only the interesting parts.

This could be combined with an AI neural network to build 3D geometry from the images, which could later lead to skipping the photogrammetry step entirely and just generating based on 2D images. From there, one could theoretically "realify" anime girls and other drawings, too. The idea is cool, and I encourage you to play around with it. I'd also say that there's a lot more you could do if you teamed up with those in the industry who have the resources you need.

 

[Mikah_zulu]

Thanks for feedback.

About neural networks. Few moths ago I've tested the technology from NVidia called NERF. In short, it recreates 3D scene from images on the fly. Looks impressive, but still not even close to quality and detalization that gives good photogrammetry rig with mesh post-processing.

That girl from my screenshots is the most top-quality scan I've found. Don't know the source of it, but for sure it is costly professional work I can't afford myself. That's why I'm talking about it here actually.

 

[Yngling]

You have to ask yourself whether this technology presents a major improvement over Daz and similar programs visually. I personally think that the screenshots are ok, especially the detailed areas, like hands, vagina and anus look better than often in Daz, the rest of the body could use a bit more texture. The strange lighting doesn't really help either, perhaps.

The other question is that, if you do need the access and consent of a person, where is the advantage over just shooting porn with a live actress? If anything, your approach will be much more expensive. Unless you want to put the models in a Honey Select kind of program, I don't see the point.

Finally, the "game" you propose seems to me very boring. Like Honey Select but worse. Perhaps if you do make a Honey Select kind of program with your girls, other people can use renders from your program to make VN's and similar. But how strong that is as a business model.... It seems like a long shot...

Real models or real images are really big cons in adult games for me. You know, real peoples are flawed (Btw don't mind me, I love all bitches.)
Just think about "Alcina Dimitrescu", "2B", etc...
References are good (and surely, must) when creating a character, but scans are bad IMO.

I'd have to agree with you on that BUT have you seen those images! Nothing has peeked my curiosity like this in quite a while nor has their been any (that I know of) inovation in adult games in long time.
If theirs anything that might change my mind on playing real image adult games it might be this sorta thing, its just you gotta start with finding really good looking people.

 

[Yngling]

Not necessarily. Since you make a model of the person anyway, you can also tweak the model however you like.

But, if I think about my "Honey Select replacement" idea, you do need quite a few models to avoid repetition...

I think it´s a great idea. I don´t know much of the technical side of it, but I remember seeing 3D Models of Pornstars a while ago and they looked exceptional. I get quite bored seeing the same character models in every other game and it would be definitely a breath of fresh air seeing new models being used.

I know it's an old post but I stumbled upon this when I was looking for something. I believe that 3D scan you're using on your scene came from VRgirlz Chloe. I downloaded some of their files from reddit and random torrent sites but I'm still looking for the rest. Too bad they abandoned the project and the website is dead, but if you check their web archives or twitter posts you probably can tell it was an ambitious project considering they were experimenting with moving 3D scan back in 2015/16. Someone in VaM community managed to put it as an assetbundle so I can view it in VR in VaM and create a scene with it. Other project such as Holodexxx is big too, but not sure how long they are going to hold up. Anyway, I checked your profile picture and found your project, if you're heading to that direction I wish you all the best, I haven't downloaded your demo yet but might give it a try later. Cheers

The problem with photogrammetry is the vertex cloud isn't usually very uniform and makes hard for optimizing.
You can write code to try and fix that issues or manually go through and do it. If you want good performance after you will end up spending good bit of time on it one way or another.

There is a better option. Scan the persons skin and face and so on. Then build a uniform model and over lay it. You can get much better performance no one will really know the difference and it will take vastly less over all time and use a lot less storage space if done right.

If the game isn't going to be actually 3D where person can move around like in an FPS and the images are just going to be rendered to still images or video you can actually reduce the model quality a hell of a lot and it will never be noticeable in the scene.

However, if you plan to do real closeups you may want to build models that have LOD systems that way you have the detail for the close ups and can reduce the detail for the more distant shots the detail isn't needed. It is better than trying to create it on the fly. That said it will add to storage space.

Someone I've been working on is a standardized model for my own stuff.
If you think how tessellation works you have a set of starting nodes you split the area creating new nodes. then you repeat the process however many number of times. Each time though you work off the prior levels nodes. You can track that progress and use it to create an LOD system. Well you can do the same thing when building a model of a car, a building and even people.
If you standardize it you can then make it so that not only can you easily change the detail level of the characters you can also use it to fit outfits and clothing and attachments on those models without any issues.

With your current idea you would need to do a lot of work to make changeable outfits either scan them wearing them or fix the models so the outfits can actually fit on them.

The point is simple you do a bit of work to create the standardized model and it saves you a lot more work in other areas.Plus you can get the performance form it be it you render images or want an actual 3D game.

Some of the models made by VRGirlz is now on sale in 3D stocks. Wonder why they shut down their project. Might be legal issue as well.

Yes, there are ton of work to create skinned realistic looking character with animations. But in the end you will always notice the difference between raw pose 3D scan and skinned model. Raw 3D scan, in my opinion, looks way more natural and intriguing even if it just a static pose.

You may use scanned mesh, texture, can create your own, create cartoon stuffs, etc...
I just don't wanna see any DAZ's 3D stuff.
