During November 2024, Aik Biermans extended the FaceToEdge transform in the pyg-team/pytorch_geometric repository to support 3D tetrahedral mesh faces, enabling workflows that require conversion of 3D mesh elements into edge indices. This work involved updating the transform to handle input faces with shape [4, num_faces] and adding comprehensive pytest coverage to validate both 2D and 3D mesh conversions. Using Python and PyTorch Geometric, Aik focused on mesh processing and test-driven development to ensure robust functionality. The update addressed interoperability needs in 3D geometry and finite element pipelines, broadening the applicability of the library for downstream tooling.
