These equations are natural … WebA Bézier curve is a sequence of control points on a parameter interval. The control points may be scalars or vectors, and there may be an number of them; we will denote the control points as p_0, p_1, \dots, p_n. The n here is the order of the Bézier curve and is one less than the number of control points.
