dod

I'm creating my own game engine. I've read these articles and this question about DOD and there was written to not use member functions and classes. I also heard some criticism to this idea.

I can write it using member functions or non-member functions it would be similar. So what are benefits/cons of that approach or when project grows, does any of these approaches give clearer and better manageable code?

With POD & non-member functions I don't have to make struct members public I can still use object id outside of engine like OpenGL does with all it's stuff, so It's not about encapsulation.

POD - plain old data

DOD - data oriented design
