Credits

ComfyUI-GeometryPack is made possible by wrapping and building upon the following amazing open-source geometry processing libraries. We are deeply grateful to the authors and communities behind each of these projects.

Library	License	Description	Homepage
manifold3d	Apache-2.0	Robust, GPU-friendly CSG/boolean operations on manifold meshes	https://github.com/elalish/manifold

License Notes

• CGAL uses a dual-license model per component. Geometric algorithm packages (Surface Mesh Simplification, Polygon Mesh Processing, etc.) are GPL-3.0. Kernel and support components are LGPL-3.0. Commercial licenses are available from GeometryFactory.
• PyMesh license situation is ambiguous — setup.py references MPL-2.0 but no formal LICENSE file is present in the repository.
• MeshLib is source-available but not OSI-approved open source. Free for evaluation and non-commercial use; commercial use requires a paid license.
• gmsh is GPL-2.0-or-later but includes a linking exception that allows use as a library without triggering GPL obligations on the calling code.
• GeometryPack itself is licensed under GPL-3.0-or-later, which is compatible with all of the above.
