Animated Bézier Curves. Play with the control points to modify the curves! These animations illustrate how a parametric Bézier curve is constructed. The parameter t ranges from 0 to 1. In the simplest case, a first-order Bézier curve, the curve is a straight line between the control points. For a second-order or quadratic Bézier curve, first we find two intermediate points that are t along the lines between the three control points. Then we perform the same interpolation step again and find another point that is t along the line between those two intermediate points. Written using the D3 visualisation library.

The latest version, Illustrator CC, is the seventeenth generation in the product line. History[edit] Versions 1–1.6 (Illustrator 88)[edit] Adobe Illustrator' was first developed for the Apple Macintosh in December 1986 (shipping in January 1987) as a commercialization of Adobe's in-house font development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop. Photoshop is primarily geared toward digital photo manipulation and photorealistic styles of computer illustration, while Illustrator provides results in the typesetting and logo graphic areas of design.

Versions 2–5[edit] Versions 6–10[edit] Adobe Illustrator 10, The last version before the Creative Suite Rebrand With true ports of the Macintosh versions to Windows starting with version 7 in 1997, designers could finally standardize on Illustrator. Versions CS–CS6[edit] CS4 was released in October 2008. Paul de Casteljau. Paul de Casteljau (born 1930 in Besançon, France.) is a French physicist and mathematician. In 1959, while working at Citroën, he developed an algorithm for evaluating calculations on a certain family of curves, which would later be formalized and popularized by engineer Pierre Bézier, and the curves called De Casteljau curve or Bézier curves. De Casteljau's algorithm is widely used, with some modifications, as it is the most robust and numerically stable method for evaluating polynomials.

Other methods, such as Horner's method and forward differencing, are faster for calculating single points but are less robust. De Casteljau's algorithm is still very fast for subdividing a De Casteljau curve or Bézier curve into two curve segments at an arbitrary parametric location. De Casteljau curves[edit] Awards[edit] Paul de Casteljau received the 2012 Bézier Award from the Solid Modeling Association (SMA).

The SMA also quotes Pierre Bézier on de Casteljau's contributions: References[edit] Pierre Bézier. Pierre Étienne Bézier (September 1, 1910 – November 25, 1999; [ˈpjɛʁ eˈtjɛn beˈzje]) was a French engineer and one of the founders of the fields of solid, geometric and physical modeling as well as in the field of representing curves, especially in CAD/CAM systems.[1] As an engineer at Renault, he became a leader in the transformation of design and manufacturing, through mathematics and computing tools, into computer-aided design and three-dimensional modeling.[1] Bézier patented and popularized, but did not invent[citation needed] the Bézier curves and Bézier surfaces that are now used in most computer-aided design and computer graphics systems.

Background[edit] From 1968 to 1979 Bézier was Professor of Production Engineering at the Conservatoire National des Arts et Métiers. With his family's consent, the Solid Modeling Association established The Pierre Bézier Award for Solid, Geometric and Physical Modeling and Applications in 2007.[1] Bézier curve[edit] Renault[edit] CAD[edit]
