During April 2025, Florian Uhlig focused on improving the stability and correctness of geometry computations in the ferdymercury/root repository. He addressed an interface mismatch and enhanced const-correctness for the ComputeNormal function within the vecgeom geometry module, aligning the derived TGeoVGShape class with the base TGeoBBox to ensure proper inheritance and type safety. By enforcing const qualifiers and clarifying interface contracts, Florian reduced the risk of runtime errors during geometry traversals. His work, primarily in C++ and leveraging his expertise in geometry and software engineering, laid a solid foundation for safer computations and future feature development in the codebase.
