Effect Function Syntax (Direct3D 9)

A function is the building block for a shader created in the high-level language. If you prefer to write shaders in a C-style language instead of in assembly language, you will want to write functions.


type id ( [ parameters ] )  
    { body }

Functions do not change parameter values in an effect.

  • type - Any valid Reference for HLSL type.
  • id - A unique name.
  • parameters - Function parameters.
  • body - The body of the function.

Functions are built from the high-level language. See Reference for HLSL.
