>This makes perfect sense when it comes to things that are not round or curved
Congratulations, you just had the same thought as the guy who invented the curve G-Code that CNC machines use to make perfect circles. Instead of representing the curve as a bunch of small line segments like a 3D modeling program might do, they instead designate a centerpoint and a radius, and where to stop and start along that radius arc. Geometry then turns those instructions into stepper motor movements. As far as I know, this hasn't been translated into 3D modeling yet, because spheres are more complex than circles. I might be wrong and just not know about it.
