Pierre Bézier was a French engineer and mathematician, best known for developing the Bézier curve, a mathematical curve that is widely used in computer graphics, animation, and automotive design. His work in the 1960s at Renault revolutionized the way designers create smooth and flexible shapes, making it easier to model complex surfaces. Bézier's contributions extend beyond curves; he also played a significant role in the field of computer-aided design (CAD). His methods have become fundamental in various applications, including 3D modeling and font design, influencing how digital shapes and forms are created and manipulated today.
