What is the difference between resolution and the size of the image. I've been reading the red book but I'm not sure if I understand?

is this a stupid question?

I think that is a common confusion between 3D graphics and 2D graphics.

OpenGL uses vectors to store object information, so in a sense there is unlimited resolution in the openGL space.

Only when the scene is rendering takes place to the screen is it converted to pixels and a set resolution like 640 x 480, 800 x 600, etc.
