Developed and delivered FaceToEdge support for 3D tetrahedral mesh faces within the pyg-team/pytorch_geometric repository, expanding the transform to handle input faces with shape [4, num_faces]. The work focused on enhancing mesh processing capabilities by enabling conversion of both 2D and 3D mesh faces into edge indices, which broadens the applicability of the library for 3D geometry and finite element workflows. Employed Python and PyTorch Geometric, leveraging test-driven development with pytest to ensure correctness and reliability. The update improved interoperability with downstream tools and included comprehensive test coverage for both 2D and 3D mesh transformations.
