Developed a comprehensive vector math library for the fungover/breeze repository, enabling precise 2D, 3D, and 4D vector operations essential for graphics and physics features. The implementation in Java applied object-oriented principles to support arithmetic operations, dot and cross products, normalization, distance calculations, and linear interpolation. Robust input validation and extensive unit testing ensured numerical reliability and correctness across all vector types. This work established a solid mathematical foundation for future performance tuning and downstream feature development. No major bugs were fixed during this period, as issues were proactively addressed through thorough testing and incremental improvements in related components.
