Vector illustrations go GIF
Article Abstract:
A guide to designing vector graphics for the World Wide Web is presented. Graphics Interchange Format (GIF) is the most common Web graphics format and is supported in all browsers. It uses interlaced images that need not be completely downloaded before the user can view them; images display at low resolution and gradually become sharper. Step-by-step instructions for creating a typical Web button as a GIF file for Illustrator 7.0, FreeHand and CorelDraw 7 are presented. The first step is to create the objects that will make up the Web graphic; the included sample uses clip art. The second step is selecting colors only from the Web palette. Step three is exporting the illustration as a GIF file. Each graphics program has its own procedure for converting files into a format easily readable on the Web.

Workshop vector art
Article Abstract:
The use of cast shadowing can add depth to graphics or text. There are a few basic steps to cast shadowing. First create the object, then copy the artwork to a second layer. The new layer is pasted directly on top of the original. The software's shear or skew feature is then used to create the illusion of a 3D perspective by moving the apparent light source. A 45-degree angle is the best place to start for most cast shadows. The shadow object is then selected and a shadow fill is applied. Shadows are generally gray, but they can be any color. The height of the light source can be adjusted by scaling the skewed shadow, increasing the scale of the shadow provides the impression of a lower light source. The objects can be backlit through the addition of reflect or mirror steps.

Isometric exercises
Article Abstract:
An isometric view of an object presents a three-dimensional perspective. Isometric views of rectangular objects can be created in several graphics programs. Regardless of the program, there are six basic steps to creating an isometric view of an object. The process starts by creating the individual panels as separate rectangles. A stroke of none should be applied to the rectangle that outlines each face. If a stroke is essential, rounded caps and joins should be used to avoid spikes. The second step is to position and size the panels, with their long sides touching. The 3D perspective is then added by shearing the side panel and then rotating it. The fifth step creates the box top with the same shearing process. Lastly, the front panel of the box is transformed.
