Transition Minimized Differential Signaling (TMDS)
A technology designed to reduce electromagnetic interference (EMI) and
improve the digital signal delivered to flat panel displays. Its encoding
algorithm converts the original 8-bit graphic data into a more fault-tolerant
10-bit signal, which is then converted back to its original 8-bit form at the
display device. The signal is also DC-balanced, allowing for the option of
transmitting the signal over fibre-optic cable. DVI connectors can
incorporate up to two TMDS links, with each “link” comprised of the
number of signals required for standard RGB output. Higher resolutions
and refresh rates than standard are possible if multiple TMDS links are
available by using multiple DVI connectors.
Trilinear Filtering
A sampling method used to produce realistic-looking 3D objects. Trilinear
filtering averages one of the bilinear filter mipmap levels along with the
standard mipmap samples.
VersaVision™
An ATI technology enabling accelerated display rotation and scaling. Any
desktop can now be rotated 90 degrees left or right, or even 180 degrees,
while maintaining the full feature set of other ATI 2D and 3D technologies,
such as SmoothVision™. VersaVision™ works with single or multiple
displays.
Vertex Shader
Three-dimensional objects displayed on a screen are rendered using
polygons, each of which is made up of intersecting triangles. A vertex is a
corner of a triangle where it connects to another triangle, and each vertex
carries a considerable amount of information describing its coordinates in
3D space, as well as its weight, color, texture coordinates, fog, and point
size data. A Vertex Shader is a graphics processing function that
manipulates these values, producing such things as more realistic lighting
effects, improved complex textures such as hair and fur, and more accurate
surface deformations such as waves rippling in a pool or the stretching and
wrinkling of a character’s clothes as he or she moves.
