SmoothVision™ 2.1
SmoothVision™ 2.1 uses an advanced multi-sampling anti-aliasing
technique that takes up to six samples per pixel, coupled with lossless
compression technology to provide maximum efficiency and performance.
It employs an adaptive algorithm that takes from 1 to 16 filtered samples
per pixel, as required, without wasting effort on the parts of an image that
would not actually be visible in the display, making the process as a whole
more efficient.
SmoothVision™ HD
SmoothVision™ HD incorporates improved anti-aliasing, anisotropic
filtering and 3Dc™ compression features designed to further enhance
image quality. Anti-aliasing performance is improved, providing better
overall detail and image quality. The enhanced anisotropic filtering ensures
sharper and clearer pictures at higher frame rates, and the new 3Dc™
compression technology makes it possible to display higher polygon counts
for 3D rendered objects.
S-Video
Short for “Separate Video,” S-Video is a type of analog video interface that
produces a higher-quality signal compared to composite video. The signal
is split into two separate channels— luminance (Y) and chrominance (C).
Sometimes referred to as “Y/C video” or “Y/C”, the connectors typically
contain 4-pins within a single connection housing and are commonly found
on consumer DVD players, VCRs, game consoles, and related devices.
Specular Highlight
The bright, usually small, intense light reflected from a 3D surface with a
high refraction value. From the intensity and spread of this highlight users
can differentiate between a “hard,” smooth surface, such as metal or
porcelain, or a “soft,” textured surface, such as fabric or skin.
Texel
Short for “texture element,” the 3D equivalent of a pixel, describing the
base unit of the surface of a 3D object, such as a sphere; for a 2D object,
such as a circle, the base unit is a pixel.
