2D
Acronym for “two dimensional,” a term applied to computer graphics that
are “flat.” Typical desktop applications such as word processors,
spreadsheet programs, or other programs that manipulate print or simple
graphics (such as pictures or line art) are generally considered to be
operating within a 2D environment, even when they include simple three
dimensional elements, such as buttons.
Pulldown
Pulldown is a telecine technique used to transfer motion picture film shot
at one frame rate to a video format at a different frame rate. Typical NTSC
video contains more frames per second than motion picture film for even
division between frames, so that every 4 frames of film can be reproduced
as 5 separate NTSC frames, the “extra frame” created by interlacing
interpolated frames. The features produces a smoother NTSC video image
from a motion picture film source, and can be used for better edge image
processing in the Vector Adaptive Deinterlacing feature within Catalyst®
Control Center.
3D
Acronym for “three dimensional,” referring to computer graphics that
appear to have volume and depth. Various modeling processes take the
representation of a three dimensional object provided by the computer
program and render it by using various lighting components, applying
textures, and setting layers of transparency or opacity as required in order
to produce a realistic representation of a three-dimensional object on a two-
dimensional display.

An ATI hardware-based compression technology that reduces the size of
