Coming to DirectX 12— Mesh Shaders and Amplification Shaders: Reinventing the Geometry Pipeline  

Alma Haage (Red Door Collaborative LLC)

D3D12 is adding two new shader stages: the Mesh Shader and the Amplification Shader. These additions will streamline the rendering pipeline, while simultaneously boosting flexibility and efficiency.  In this new and improved pre-rasterization pipeline, Mesh and Amplification Shaders will optionally replace the section of the pipeline consisting of the Input Assembler as well as Vertex, Geometry, Domain, and Hull Shaders with richer and more general purpose capabilitiesThis is possible through a reimagination of how geometry is processed.
