Have you ever used a graphing calculator?
If you create a graph of an equation on a graphing calculator, the calculator will be able to draw it no matter what your zoom level is. That’s because the graph itself is just pure math; the calculator is computing what it looks like on-the-fly based on the math.
Some people make a hobby out of trying to draw shapes and pictures in graphing calculators. If you find the right math equations and plug them into a graphing calculator, the calculator will draw your drawing for you.
Vector graphics work like that. No… not *like* that. That is *literally exactly* how vector graphics work. Vector graphics files are just lists of math equations. When it’s time to draw the graphic to the screen, the computer solves the equations, exactly how a graphing calculator would, and shows you the result.
You can infinitely zoom in on it because, under the hood, it’s just pure math. Math doesn’t end. All zooming in farther does is change the computation the computer has to do to show you the image, which it will happily do on-the-fly.
