Tessellation & Geometry Shaders
Surface Shaders have support for simple tessellation and displacement. See documentation on Surface Shader Tessellation for more information.
When you manually write a Shader program, you can use the full set of DX11 Shader model 5.0 features- including Geometry, Hull and Domain Shaders.
确实如此 。。。。。只有surf支持
