32 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.
