Worked on the openmobilemaps/maps-core repository to deliver GPU-accelerated tessellation and rendering enhancements for map visualization across Android and iOS platforms. Developed quad and polygon tessellation features using C++, OpenGL, and Metal, introducing new vertex structures, shader optimizations, and compile-time toggles to support both legacy and advanced rendering paths. Improved rendering fidelity and performance by refining the graphics pipeline, optimizing shaders, and ensuring thread safety. Addressed platform-specific needs by integrating Android and iOS-specific tessellation logic and fixing a 3D rendering bug in IconLayer, resulting in smoother, more reliable 2D and 3D map rendering across devices and simulators.

Nov 1, 2025November 2025 performance summary: Delivered a major graphics pipeline enhancement by introducing quad tessellation support for openmobilemaps/maps-core, enabling higher visual detail and flexible rendering for both 2D and 3D objects. Achieved end-to-end completion of the polygon mask tessellation feature, stabilizing the tessellation pipeline from refactor and partial implementation to a complete, robust solution. Initiated Android-specific quad tessellation work to expand cross-platform support. These efforts improve rendering fidelity, user experience, and platform parity, while establishing a solid foundation for future GPU-accelerated features and performance optimizations.
