During July 2025, contributed to the mrdoob/three.js repository by addressing a rendering issue related to Ambient Occlusion (AO) in Three.js scenes. Focused on improving AO reliability and visual fidelity, the work involved modifying the GTAOPass to exclude Line2 primitives, such as Points and Lines, from AO calculations. This targeted JavaScript fix eliminated visual artifacts and ensured correct AO results across diverse scenes. Demonstrated a strong understanding of 3D rendering, graphics programming, and post-processing effects by implementing a minimal-impact change to the rendering pipeline, which reduced post-release QA issues and enhanced the overall quality of AO in Three.js projects.
