How do i open .FP files?

so i looked up fp files on google and i heard it’s under OpenGL, but i have no idea how to open them, it’s 3D imaging i believe, if anybody knows please let me know, thanks

An extension doesn’t mean much because the user chooses it. Could be anything (a few possibilities: FP).

What’s in it? Is it a text file or a binary file? If text, what are the first 5 lines?

In the context of OpenGL, this could be a fragment shader (i.e. source code) written in some shading language (e.g. GLSL, assembly, etc.). Then again, depending on what’s in it, it might not have anything to do with OpenGL.
