Meshing around with shaders coming with DirectX Ultimate

In late 2019 Microsoft announced it would make a major upgrade to its Windows API DirectX12. The company said it would add two new shader stages: the Mesh Shader and the Amplification Shader. Mesh shaders incorporate most aspects of Vertex (VS) and Geometry shaders (GS) into one shader stage by processing batches of vertices and primitives before the rasterizer. The VS, HS, DS, and GS shaders are replaced with an Amplification Shader.  (See the GPU Pipeline Evolution diagram. It will help.) A mesh shader is a new type of shader that combines vertex and primitive processing. VS, HS, DS, and
