I'm not into 3D printing, so I'm unsure of what viable means in that context, but for photogrammetry in general, I've had success generating 3D models of little figurines/statues with just a bunch (~15-20) of photos from my cell phone using Meshroom[1] followed by light touch up in Blender[2] to separate the environment from the model. Both are open source.
Recent Sony phones (1-2 years old) come with an app that does this with _really good_ results. AFAIK it only uses standard camera image + some AI magic.
Thank you for this! I have thought about how neat this would be since FaceID first came out, but I had always assumed the IR camera’s API wasn’t available to third parties. This is awesome.
Edit: Yikes. A bunch of these 3D scanner apps are very shady. Requiring an account and/or subscription. There is no way I’m sending 3D scans to some private server. I did find one that seems on the level: STL Maker. I’m sure there’s others, but users should be careful.
