No GPU tessellation, displacement in the vertex modifier When you use tessellation, the shader is automatically compiled into the Shader Model 4.6 target, which prevents support for running on older graphics targets.More info See in Glossary, no isoline tessellation. Only triangle domain - no quads A primitive object that resembles a plane but its edges are only one unit long, it uses only 4 vertices, and the surface is oriented in the XY plane of the local coordinate space.
Surface shaders can optionally compute phong tessellation to smooth model surface even without any displacement mapping.Ĭurrent limitations of tessellation support:. Here you’d typically to displacement mapping. When tessellation is used, “vertex modifier” ( vertex:FunctionName) is invoked after tessellation, for each generated vertex in the domain shader A program that runs on the GPU. That function computes triangle edge and inside tessellation factors. Tessellation is indicated by tessellate:FunctionName modifier.
