I would say that’s pretty bad. You want to render only what is needed, not the entire scene. It’s bad for performance otherwise. It might be a good teaching tool, but you would almost never do it this way in a real game.
Also, typically you want to render a symbolic representation, show enemies as red dots, ammo pick-ups as yellow bullets, and health pick ups as white crosses, for example.
I have a minimap module for meep, it’s pretty complex as a result of applying multiple optimizations but it does what I have described as its core.
