Per Khan Academy Pixar-in-a-Box (parametric curves), a CUBIC Bezier curve is defined by how many control points?
A4 (P0, P1, P2, P3)
B3 (a quadratic)
C5 or more always
D2 endpoints only
Answer & Solution
Correct answer: A. 4 (P0, P1, P2, P3)
Pixar-in-a-Box Curves: cubic Bezier needs 4 points. P0 and P3 are endpoints; P1, P2 control tangents/curvature.
