Worked on enhancing collision detection accuracy and code maintainability in the NVIDIA/warp repository, focusing on the physics simulation pipeline. Addressed a bug in box-box collision handling by recalculating collision normals using the transformed center of box A, replacing the previous world-space translation method to improve simulation determinism and reduce edge-case inconsistencies. Utilized Python and C++ (via Python bindings) to implement these changes, ensuring more reliable collision outcomes. Additionally, refactored the code by removing a redundant assignment in the collision path, streamlining the logic without altering functionality. The work contributed to improved stability and clarity in the codebase.
