Desktop Publishing, involves the use of a computer and specialized software to combine text and graphics to create a document that can be printed on a laser postscript printer, proofed on a IRIS proffer. Desktop publishing is a multiple-step process involving various types of software and equipment. The original text and illustrations are generally produced with software such as word processors and drawing and painting programs and with photograph-scanning equipment and digitizers. |
The field of computer graphics concerned with generating and displaying three-dimensional objects in a two-dimensional space (e.g., the display screen). Whereas pixels in a 2-dimensional graphic have the properties of position, color, and brightness, a 3-D pixels adds a depth property that indicates where the point lies on an imaginary Z-axis. When many 3-D pixels are combined, each with its own depth value, the result is a three-dimensional surface, called a texture. In addition to textures, 3-D graphics also supports multiple objects interacting with one another. For example, a solid object may partially hide an object behind it. Finally, sophisticated 3-D graphics use techniques such as ray tracing to apply realistic shadows to an image. |
