Paul de Casteljau

Paul de Casteljau was a French mathematician known for developing a method to create smooth curves called Bézier curves. His algorithm uses a process of linear interpolation—essentially blending points—repeatedly to generate a curve that perfectly follows specified control points. This technique allows designers and engineers to precisely shape complex, flowing lines used in graphics, animation, and CAD applications. De Casteljau’s method is favored for its numerical stability and versatility, making it a foundational tool in computer-aided design and digital art.
