Glossary

LOSSARY

Three-dimensional

3D-DDI

3D device driver interface, software interface (3D-API) from Microsoft, higher level

3D-APIs like OpenGL and 3DR may be implemented in Windows 95

3DR

3D software interface (3D-API) from Intel, supporting Microsoft's GDI DDI, DCI and

3D-DDI

ADI

AutoDesk Device Interface

AGP

The Accelerated Graphics Port (AGP) is a new technology developed by Intel for

Pentium II based systems. AGP is a dedicated graphics port, separate from the

existing PCI bus. Having a dedicated graphics port does improve overall system

performance; e.g. AGP allows textures used in 3D graphics applications to be

accessed directly from system memory. The rate of AGP 1X information transfer is

twice as fast as PCI transfer rates.

Alpha blending

Creating transparent materials with the help of additional information for each pixel.

Analog

Continuously varying electronic signal to reproduce information. Compare digital.

Analog Display

Monitor that uses variable color control voltages to display a very large number of

colors but requires very few inputs.

ANSI

American National Standards Institute.

Anti-aliasing

Interpolating the colors of neighboring pixels in order to avoid the 'pixel look' of an

image.

API - Application Programmers Interface

An API is a series of software commands used by programmers to implement a

specific set of instructions, such as the creation of 3D graphics, and make those

instructions available to other programs, or to make specific functions of your

operating system, such as Direct3D, available to an application.
