Ok I've managed to put a quad on my screen with a png texture on it, using lwjgl.
But I've read a lot of stuff about lwjgl and opengl the last few days, and I remember that using quads is probably not the most efficient way to display a lot of 2d graphics on the screen.
Is there another, more efficient way of displaying 2d graphics, I think it has something to do with sprites? And something I also havent looked into but might have to do with it is fustrum. Anyway I'm unsure which way to go now. My goal is to make a 2d isometric game, and I know about orthographic projections.
I was a bit unsure whether to put this in lwjgl or newbie forum, because I guess it's both
