Worked on the facebook/igl repository to deliver Alpha-to-Coverage (A2C) rendering support across multiple graphics backends, including Vulkan, Metal, D3D12, and OpenGL. This involved plumbing the alphaToCoverageEnabled flag through igl::RenderPipelineDesc and integrating it with each backend, enabling improved transparency handling and enhanced visual quality in composited scenes. The implementation required in-depth knowledge of graphics programming and proficiency in C++, as well as experience with modern rendering APIs. By addressing cross-backend consistency, the work contributed to a more robust rendering pipeline, ensuring that transparency features behave uniformly across all supported platforms in the codebase.
