WebIN GLSL a function can also declare its parameters as outputs of the function. The return type can have any type, except an array. The parameters of a function have the following qualifiers available: in – for input parameters. out – for outputs of the function. The return statement is also an option for sending the result of a function. WebThe main function is called for every fragment just like the vertex shader main function is called for every vertex. Colors in GLSL are 4-component vectors with the R, G, B and alpha channels within the [0, 1] range. Unlike gl_Position in the vertex shader, there is no built-in variable to output a color for the current fragment.

WebFeb 3, 2012 · In GLSL, a subroutine is a mechanism for binding a function call to one of a set of possible function definitions based on the value of a variable. Subroutines therefore provide a way to select alternate implementations at runtime without swapping shader programs and/or recompiling, or using if statements along with a uniform variable.

WebSuch a change is beyond the scope of this extension. No effort was made to make subroutine uniforms generic enough to support other potential usages.
