Worked on the bevyengine/bevy repository to enhance the mesh rendering pipeline by implementing triangle-indexed ray-mesh intersection in Rust. This update allowed the system to return the triangle index at each ray hit, enabling accurate access to UV coordinates and texture colors for improved shading and texture sampling. Addressed data alignment issues to ensure that per-hit information corresponds to the correct triangle, not just a vertex, which improved both rendering fidelity and debugging capabilities. Leveraged skills in 3D graphics programming and game development to deliver clear, traceable commits that resolved a longstanding issue and refined the accuracy of material lookups.
