Anyone here into photogrammetry? I'm slowly learning 3d modeling but I'm curious if photogrammetry is ever really used in any professional works? I know people scan faces all the time but I'm not really familiar with it. Only time I remember someone really using it was this autist for one of his vids:

timestamp should work at 19:26. But that's it. Feel free to use this thread to talk about anything related to the scanning itself or working on models afterwards, I'm also curious about that.

It's scanner, not photogrammetry. Photogrammetry, for all that I tried, produces some shitty glitchy mesh with barely any use.

Ok, so no photogrammetry. Got it. Is model scanning anywhere near competent or user-friendly, then?

There’s an iOS app called Polycam that’s pretty amazing but it costs like 20/month.

Photogrammetry is definitely a part of the professional pipeline. It's difficult to tell you why when you have not clearly stated the use case.
It obviously has a lot of application for video game for instance. Call of Duty and Battlefield are a prominent patrons of this tool.

There's a very good introduction video to photogrammetry that I would recommend: https://www.youtube.com/watch?v=Il6LVXqSlRg

pic related, on of my works

This video is INCREDIBLY helpful, thank you anon! Do you have anything else you want to mention or some advice or anything? I always love to hear from people who know more than me.

Photogrammetry is a complete waste of time, I tried multiple free and pirated several proprietaty softwares, they all have issues. They even have problems replicating a rendered 3d human meshes in virtual turntable. At best, you'll get some lump of polygons to sculpt from. And I'm not even talking about large objects. Get a 300$ 3d scanner instead.

Saar, you are a moron, saar. Like I said, photogrammetry is useful for toying around, or something like really large objects shot from drone, for anything else there are 3d scanner, which fortunately will only become cheaper like 3d printer did:

Is there anything stopping me from just using one of those 3d scanners and just never touching 3d modeling?

No. As long as you set up the proper workflow.

I have a family member that wants a 3d scan of their head to 3d print into a bobble-head, what's the best free/cheap solutions for this? Shit I've tried in the past either haven't worked, had a huge paywall, or produced a model I couldn't even touch up in Blender

check out etsy, you might be able to get one custom-ordered from there.

It is MORE user friendly.
However get ready to hit your wallet hard to buy the HARDWARE.

Or search a long time for the good budget 3D scaner.

I hear POP 3 is the best budget scaner.
>is it used
There are games who used 3D scaning of rocks and for terain.

LMFAO. It is free for android however gives like 6 free photos.

Polycam is 100% ass. The geometry gets fucked up and is warked. You can not move from the spot you stand in only rotate and the geometry is fucked.

Not usable for anything other then Abstract art or scaning the room you are in in 3 minutes.

This all of this.
Photogrametry is shot because it tries to work with photos.
Most 3D scaners use more like Structured light or depth sensors.
Photogrametry is a TOY

3d scanets are infinetly more useful then 3d printers.

One is a tool that can bring physical models into the computer.
The other is a retarded toy that poisons you and can only spit out TOXIC plastic crap CnC is superior to 3 d printing for all civilian cases

LOL.
All 3d scaning is limited.
There are angels these scaners can never scan.

Also do you seriously think you are going to sculpt all your characters in real clay before scaning them?

instead of simply modeling in the computer on any 2024 gaming laptop?

I tried the free version in a museum and was able to get decent models of the works without a ton of effort. Might work a bit better on iOS with its proper camera software.
