Anisotropic Filtering
A technique that preserves the surface details of an object as it recedes into
the distance by utilizing and blending together the object’s texture maps.
This makes 3D objects appear more realistic as the detail of their surface
texture is retained in a smooth, seamless fashion on the sections that move
or fade away into the background.
Anti-aliasing
A method that smooths out the jagged edges of a curved object. A black
curved line on a white background displayed on a computer screen will
have some jaggedness along its edges due to the inherent limitations of
using discrete pixels to display the image. Anti-aliasing smooths out this
jaggedness by filling in the white spaces between the jagged edges with
varying shades of grey.
Aspect
A group of related features in ATI’s Catalyst ™ Control Center software. For
example, the Color aspect clusters together controls that handles gamma,
brightness, contrast, and other features relating directly to the display of
color. Similarly, the 3D aspect provides a set of related controls dealing
with such features as anti-aliasing, anisotropic filtering, mipmap details
levels, and more.
Aspect Ratio
The proportions of a display are expressed as a ratio of its width and height.
Common ratios include 4:3 for TVs and CRTs, 5:4 for LCDs, and 16:9 for
widescreen displays.
Avivo™ Color
Avivo™ Color is an advanced feature within Catalyst ™ Control Center,
providing the user with precise control over how color is displayed on a
monitor. Avivo™ Color provides tools to adjust the Hue and Saturation
values on a per-monitor basis, making it possible to optimize the use of a
