Like the title says, I just packaged Meshroom (and all the adjacent dependencies) for Debian! This is a fancy photogrammetry toolkit that uses modern software development methods. "Modern" meaning that it has a multitude of dependencies that come from lots of disparate places, which make it impossible for a mere mortal to build the thing. The Linux "installer" is 13GB and probably is some sort of container, or something.
But now, if you have a Debian/sid box with the non-free repos enabled, you can
sudo apt install meshroom
And then you can generate and 3D-print a life-size, geometrically-accurate
statue of your cat. The colmap package does a similar thing, and has been in
Debian for a while. I think it can't do as many things, but it's good to have
both tools easily available.
These packages are all in contrib, because they depend on a number of non-free things, most notably CUDA.
This is currently in Debian/sid, but should be picked up by the downstream distros as they're released. The next noteworthy one is Ubuntu 26.04. Testing and feedback welcome.
