1. the end point of each section is the starting point of the following section, and
2. the derivatives across that dual point line up.
Unless, of course, you want discontinuities; then you don't even need 2.
Unless you want sharp corners, of course. Then you don't even need 2.
We'll cover three forms of poly-Bézier curves in this section. First, we'll look at the kind that just follows point 1. where the end point of a segment is the same point as the start point of the next segment. This leads to poly-Béziers that are pretty hard to work with, but they're the easiest to implement:
