CAD Curve Basics

A boundary representation (BREP) is a data structure used to represent all things topological: 3D meshes, 2d vector curves, volumes, etc. This post is about what makes a good boundary representation for CAD, tailored to support complex curves in a mathematically intutive (and correct) way.

What Is A Curve

What is a curve? A curve is a multidimensional function that is parameterized with one variable.
