images much more smoothly and quickly than was previously possible with
PCI video cards; AGP runs at several times the bus speed of PCI and
employs sideband addressing, so multiple data transfers between the
graphics processor and the computer can take place concurrently. AGP is
currently being phased out in favour of PCI Express® (PCIe™) on PC
systems.
Alpha Blending
Alpha blending is used in 3D graphics to create transparent or opaque
effects for surfaces such as glass and water. Alpha is a transparency value,
so the lower the value, the more transparent the image looks. It is also used
in animations to produce such things as fading effects, where one image
gradually fades into another.
Alternate Frame Rendering
A graphical load-balancing scheme where two graphics cards are used to
render alternate frames of the display. This configuration increases the
detail of the 3D objects each card can render, as each card handles half of
the total number of frames. Essentially, each card has more time to render
a scene, delivering a noticeable increase in 3D detail. This type of graphical
operation is only available in Radeon® CrossFire™ graphics cards running
Microsoft® Direct 3D® and OpenGL® games or applications.
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
