Question:
The parametric vector form of a B-spline curve was defined in the Practice Problems as
where p0, p1, p2, and p3 are the control points.
a. Show that for 0 ≤ t ≤ 1(x)t / is in the convex hull of the control points.
b. Suppose that a B-spline curve x(t) is translated to x(t) + b (as in Exercise 1). Show that this new curve is again a B-spline.
Data From Exercise 1
Suppose a Bézier curve is translated to x(t) + b. That is, for 0 ≤ t ≤ 1, the new curve is
Show that this new curve is again a Bézier curve.
