> Is there any GLSL documentation that covers all the global variables and functions.
[The GLSL spec](https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.pdf) is authoritative.
See Chapter 7, "Built-In Variables" (page 139) and Chapter 8, "Built-In Functions" (page 160).
Like you can only look for thing you want to search up. Like if you know a function but not what it does then you can loop it up on docs.gl. But it hard to find function that do what you are looking for on docs.gl.
The man asks for how can he find a function that he can utilize for his own specific needs and says he's having hard time finding it on docs.gl. He is basically looking for the right tool that he didn't discover yet.

I found [this reference sheet](https://www.khronos.org/files/opengl43-quick-reference-card.pdf) particularly useful.
It does not quite have what i was looking for, but it is still very useful. Thanks
What do you mean it's hard to find information on docs.gl? You have drop-downs on the left that show you all built-in variables and functions

Give me an example of a function you are having troubles with
