Worked on the OpenTTD/OpenTTD repository to address a rendering issue affecting bridges that support both road and tram traffic. Focused on improving graphics rendering by enabling simultaneous display of road and tram catenary sprites, this effort involved expanding sprite sequence arrays and decoupling the catenary drawing logic for independent rendering. The solution, implemented in C++ and leveraging game development techniques, eliminated visual glitches and ensured accurate overhead wire representation. By refining the rendering pipeline and enhancing sprite data structures, the work improved visual fidelity and user experience, aligning with the project’s goal of realistic infrastructure depiction in complex traffic scenarios.
