In Graphic Realms
Cybersketching is entirely dependent upon graphics programs, applications that enable images to be created and modified on a computer. There are two basic types of computer graphics – vector graphics and bitmaps. Vector graphics are best suited to computer-aided design, producing technical drawings and designs featuring illustrations with sharp-edged geometrical patterns (Figure 7.1). As mathematically based constructs that use combinations of points, lines, curves, and polygons, vector graphics are capable of being scaled in size without any loss of detail; they are also economical in the amount of computer memory they occupy. Vector images are easily converted to bitmaps (see below).
