Huang / Zhou / Niessner / Shewchuk / Guibas quadrangulation (SIGGRAPH 2018). Same production need as Instant Meshes: turn a triangle dump into quads you can UV. The README says MIT. LICENSE.txt is a BSD-3-Clause text, not MIT. This entry follows the license file. Eigen's Sparse Cholesky path is LGPL unless you pass -DBUILD_FREE_LICENSE=ON. Pages fetched on 2026-08-24 do not say the exported mesh is BSD. The remesher is; the input scan is not.

Maintenance: no push to the GitHub repository hjwdzh/QuadriFlow since 2019-12-07, per the GitHub API on 2026-09-26.
Build from source. No first-party Windows zip on the repo page on 2026-08-24
LICENSE.txt also has a "you are under no obligation to provide Enhancements" paragraph. That is extra BSD language, not a second grant for game assets
Prefer Instant Meshes if you want a GUI. QuadriFlow is the batch/research CLI sibling
