Worked on the mitsuba-renderer/mitsuba3 repository to enhance the stability and accuracy of the renderer’s AOV pipeline. Focused on a targeted bug fix involving the computation of UV partial derivatives, ensuring that duv_dy is correctly calculated for AOVs by invoking si.compute_uv_partials(ray). This adjustment introduced an explicit computation path for UV partials, which improved the reliability and consistency of UV-based AOVs and reduced rendering artifacts related to missing data. The work was implemented in C++ and leveraged expertise in 3D graphics and rendering, addressing a nuanced issue that directly impacted the quality of rendered outputs in Mitsuba 3.
