I once bought S/N 000136 of the very first Adobe Illustrator a long time ago (bezier curves). Now I know how the others work. Very nice! Greg L 06:35, 26 February 2007 (UTC) Oppose, Support — While the images are very pretty, I don't think they're very effective at giving an intuitive idea of how a Bezier curve is constructed. The ...
Adjustment handles are a way to facilitate the construction of e.g. a cubic Bézier curve. In graphical user interfaces, the control element adjustment handle is a small box that appears on the corners and edges of a selected element such as another graphical control element like a window. This allows the user to alter size or shape.
The mathematical basis for Bézier curves—the Bernstein polynomials—was established in 1912, but the polynomials were not applied to graphics until some 50 years later when mathematician Paul de Casteljau in 1959 developed de Casteljau's algorithm, a numerically stable method for evaluating the curves, and became the first to apply them to computer-aided design at French automaker Citroën ...
The control handles define the shape of the curve on either side of the common node, and can be manipulated by the user, via the software. [ 2 ] Bézier curves were adopted as the standard curve of the PostScript language and subsequently were adopted by vector programs such as Adobe Illustrator , CorelDRAW and Inkscape .
The geometry of a single bicubic patch is thus completely defined by a set of 16 control points. These are typically linked up to form a B-spline surface in a similar way as Bézier curves are linked up to form a B-spline curve. Simpler Bézier surfaces are formed from biquadratic patches (m = n = 2), or Bézier triangles.

A vector graphic editor is a computer program that enables its users to create, compose and edit images with the use of mathematical and geometrical commands rather than individual pixels. This software is used in creating high-definition vector graphic images that can be scaled indefinitely without losing their quality.
The spline's on-curve control points are placed at the circle's horizontal and vertical tangent points and at displacements (79, 79) from the center and its reflections about the X and Y axes. Off-curve control points are placed at the intersections between the horizontal and vertical tangent line and 45-degree lines from the diagonal control ...
