The Comparison Between Bezier and B-splines Curves Using MATLAB

Curves are characterized by their multiple uses in various fields, especially in mathematics, engineering, and computer science. This study aimed to find a comparison between Bezier and B-spline curves using MATLAB. The study followed the applied analytical approach. The study reached the most important results, which are that when a point in the B-spline curve changes, the curve changes locally around that point, while when a point in the Bezier curve changes, the curve changes completely. And the number of control points in a B-spline curve is one-third less than the number of control points in a Bezier curve. Furthermore, the control points in a B-spline curve are not tangent to the curve's path, whereas in a Bezier curve, the control points are tangent to the curve's path. Based on the results, we found that the B-spline curve performs better than the Bezier curve. The study also utilized MATLAB to drive both Bezier and B-spline curves, allowing for a more precise observation of local and global effects. We recommend that researchers conduct further observations regarding the local and global effects of both types of curves and utilize these findings in mathematical, engineering and medical fields.
