During December 2024, Jason contributed to the shadPS4 repository by implementing RectList primitive type support in SPIR-V generation for geometry shaders. He mapped RectList primitives to the Triangles execution mode and set the vertex count to three, ensuring alignment with the graphics pipeline’s requirements. This work improved shader recompiler compatibility across various primitive types, reducing translation issues during shader reloads. Jason’s efforts focused on graphics programming and shader development using C++, with a deep understanding of SPIR-V. The feature addressed a specific gap in geometry shader support, demonstrating careful attention to pipeline integration and cross-type compatibility within the project.
