Illustration, graphisme. Illustrator CS3. Bézier curve. The basis functions on the range t in [0,1] for cubic Bézier curves: blue: y0 = (1 − t)3, green: y1 = 3(1 − t)2 t, red: y2 = 3(1 − t) t2, and cyan: y3 = t3. A Bézier curve is a parametric curve frequently used in computer graphics and related fields. Generalizations of Bézier curves to higher dimensions are called Bézier surfaces, of which the Bézier triangle is a special case.
In vector graphics, Bézier curves are used to model smooth curves that can be scaled indefinitely. "Paths", as they are commonly referred to in image manipulation programs,[note 1] are combinations of linked Bézier curves. Paths are not bound by the limits of rasterized images and are intuitive to modify. Bézier curves are also used in the time domain, particularly in animation and user interface[note 2] design. The mathematical basis for Bézier curves — the Bernstein polynomial — has been known since 1912, but its applicability to graphics was understood half a century later.

There are a lot of color books available in Illustrator to discover a wide range of swatches. Most popular among them are the Pantone Color Books and default CMYK and RGB swatches. In this tutorial, we will learn how to create a wide range of custom swatches using the color blending methods. In the end, we will learn how to organize these swatches into Color groups. Final Image Preview Below are some of the swatches we'll be creating in this tutorial.
Tutorial Details Program: Adobe Illustrator CS3Difficulty: IntermediateEstimated Completion Time: 1 Hour Step 1: Understanding the Color Blending Methods Before proceeding towards the meat of the tutorial, let’s have a brief look towards two different types of color blending methods. Method 1. This method blends two or more colored objects by generating a series of intermediate objects between them. Method 2. For our purpose, we will use the second method in this tutorial. Step 2: Create a Dummy Swatch. Illustrator’s Blend Tool: A Comprehensive Guide. A few times a each month we revisit some of our reader’s favorite posts from throughout the history of Vectortuts+. This tutorial by Simona Pfreundner was first published on November 14th 2008. In Adobe Illustrator, the Blend Tool can help you create impressive color blends. But there is more to it than you might know. This comprehensive guide can help you unlock your creative potential and teaches the features, shortcuts, and in depth methods that the Blend Tool has to offer.
Introduction If you are using Illustrator for detailed imagery creation, the Blend Tool can be your most important tool. Exercise File Below is an screenshot of the Exercise file that accompanies this tutorial, and is available to PLUS Members. 1. Overview and Keyboard Shortcuts (see image below for Menu items): 2. You can make a blend between open paths like lines Or between closed paths like shapes And blends between blends 3. Under Object > Blend > Blend Options, you will find different settings that you can apply: 4. Logos. Vector graphics.
Example showing effect of vector graphics versus raster graphics. The original vector-based illustration is at the left. The upper-right image illustrates magnification of 7x as a vector graphic. The lower-right illustrates the same magnification as a raster (bitmap) graphic. Raster images are based on pixels and so when scaled there is a loss of clarity, while vector-based graphics can be scaled by any amount without degrading quality.
Overview[edit] Computer displays are made up from grids of small rectangular cells called pixels; the term comes from "picture elements". The picture is built up from these cells. A vector-based image of a round four-color swirl. Modern displays and printers are raster devices; vector formats have to be converted to raster format (bitmaps – pixel arrays) before they can be rendered (displayed or printed). Standards[edit] The World Wide Web Consortium (W3C) standard for vector graphics is Scalable Vector Graphics (SVG). Applications[edit] Information[edit]
