Explain bezier curve and its properties

WebA basis spline, or B-spline, is a piecewise polynomial function with specific properties that determine the polynomial degree/order. The idea behind using a B-spline curve is to determine a unique polynomial representation of a set of data, whether that data be structural points in 3D space or a set of data on a graph. WebOct 6, 2024 · Bézier curves are the powerful mechanism for modeling in computer-aided geometric design (CAGD) and computer graphics (CG). Bézier curves have a lot of applications in the areas of science, engineering, and technology such as: railway route or highway modeling, networks, animation, computer-aided design system, robotics, …
