Naming conventions for glsl outs and ins

Question

After following several different tutorials on OpenGL shaders, I noticed they all use different naming for the outs and ins.

For instance, I've seen ex_color vFragColor, ModelViewMatrix, mvMatrix, etc.

It would be nice if my shaders would be compatible with some other shaders out there without having to rename everything. Is there some kind of naming scheme, or standard I could follow that is more or less common?

Answer 1

There is no naming convention for interface variable names. You should use whatever works and makes sense for your needs.

Also, there's no need to be "compatible" with other people shaders if you don't copy and paste their code into your own.
