Worked on the shadPS4 repository to enhance geometry shader support by implementing RectList primitive type handling within SPIR-V generation. This involved mapping RectList primitives to the Triangles execution mode and setting the vertex count to three, ensuring alignment with graphics pipeline requirements. The approach improved shader recompiler compatibility across various primitive types, reducing translation issues during shader reloads. The work was carried out using C++ and focused on graphics programming and shader development, addressing compatibility gaps in the pipeline. Over the course of the month, contributed one feature that formalized RectList handling, with no bugs reported or fixed during this period.
