I need to implement some slightly custom tessellation. unity - Accessing vertex Input in surf directly without vert's out ... 关于D3D11,你必须了解的几件事情 Tessellation is indicated by tessellate:FunctionName modifier. The topological configurations improve the efficiency of the vertex cache so as to avoid redundant shader operations. Notice that the sphere is red. Shader Unity ShaderGraph vertex displacement / tessellation (example snow) Writing a dx11 tessellation shader. - Unity Answers Name it Waves and open the script. It also computes the required tessellation level based on distance to the eye, screen space spanning, hull curvature, or displacement roughness. to write Shaders in Unity using HLSL
