Page Description
Shader program fundamentals Learn about writing shader programs in HLSL in Unity, and vertex and fragment shaders.
Add an HLSL shader program Use the HLSLPROGRAM directive to add a shader program to a shader pass.
Duplicate HLSL in multiple programs Use the HLSLINCLUDE directive to add a block of HLSL code that the compiler duplicates in each shader program.
Shader input Resources for HLSL data types, using 16-bit precision, input vertex data, and texture samplers.
Include another HLSL file in a shader Use the HLSL #include directive, or the #include_with_pragmas directive if you want to share #pragma directives between multiple files.
Pass information to the shader compiler Use the #pragma or #define_for_platform_compiler directives to pass information to the shader compiler.
Writing shaders for different graphics APIs Write shaders to take into account how graphics rendering differs between different graphics APIs.
GLSL in Unity If a platform supports OpenGL Core and OpenGL ES, you can write OpenGL Shading Language (GLSL) shader programs in Unity.
