Perspective wasn't always a grid overlay in your drawing app. In 1413, Filippo Brunelleschi stood in Florence with a mirror and a painting, proving buildings could shrink mathematically toward a single point. Artists spent the next 200 years mastering this through tedious ruler work and geometry.

By the 1800s, art schools standardized the teaching: draw horizon lines, mark vanishing points, connect everything with straight edges. Students filled notebooks with cube exercises before touching organic forms. It took months to internalize.

The 1980s brought CAD software. Suddenly architects could rotate 3D models instead of calculating angles manually. Digital artists got perspective grids that snapped objects into place automatically.

Today's illustration software does the math invisibly. You drag a box, it conforms to your preset perspective. What took Renaissance masters years now happens in seconds. But here's the catch: the software can't decide which perspective tells your story better. That judgment still requires understanding the principles Brunelleschi proved 600 years ago. The tools accelerated execution, not the thinking behind composition choices.
