Photographs into 3D!
This is a community to share and discuss 3D photogrammetry modeling. Links to different 3D models, images, articles, and videos related to 3D photogrammetry are highly encouraged, e.g. articles on new photogrammetry software or techniques. Feel free to post questions or opinions on anything that has to do with 3D photogrammetry. The point is to have a place where we can help each other out. Photogrammetry is the process of converting a series of photographs into a textured 3D model.

Photogrammetry allows generating 3D data from images.
Free photogrammetry software:
- Meshroom - I use this. Currently requires Nvidia graphics, but work is being done on that.

You're now appointed as a mod. I hope you don't mind if I also copy your sidebar text here, since it was quite a bit better than mine.
Nope, took that sidebar for Reddit anyway.
I got into photogrammetry earlier this year and was sad to see that Meshroom could only work on CUDA graphics cards. I found a fork of meshroom called MeshroomCL, that had some of the features ported over to opencl. However I had issues with getting "Camera: Not Reconstructed" errors on images.
I probably should have looked into other non cuda alternatives, but ended up buying a new GPU instead. My previous one was 7 years old, so it was time for an upgrade regardless. The regular version of meshroom is working fine, as long as I capture enough images of the target object.
