meshmixer is an experimental 3D modeling tool for making 3D mashups without too much hassle.
The goal of meshmixer is to make it easy to compose new 3D models from existing meshes.
Still very much used, but not in development at this point in time.
But I don't see it here, and can't seem to add it, though it seems like others have also unsuccessfully tried to add it.
Meshlab is not maintained since 2016
