How to create cubic bezier curve using control points?

WebJul 9, 2024 · 1 Answer. Sorted by: 1. A cubic bezier curve starting from point P 0, ending at point P 3 with two control points P 1 and P 2 is represented by the following, B ( t) = P 0 ( 1 − t) 3 + 3 ( 1 − t) 2 t P 1 + 3 ( 1 − t) t 2 P 2 + t 3 P 3, t ∈ [ 0, 1] In your question, P 1, P 2, P 3 are given but P 0 is not satisfied. May be it is ( 0, 0). WebFirst, we assign a parameter value t i to each point P i. The usual way to do this is to use chord-lengths -- you choose the t i values such that t i − t i − 1 = ‖ P i − P i − 1 ‖. Then you compute x as a function of t. The calculation is the one you already know, but it's just x = f ( t) instead of y = f ( x).
